Getter

A getter is a public accessor method, used in object-oriented programming, which returns the value associated with a private member of a class.

Setter

Setter is public mutator method, used in object-oriented programming, which gives new value to a private member of a class.



Property value name

Example

"And as already noted setter getter are not implemented in ie;also i m not sure about how wise it is to have a setter that is the same name as the property it sets"

"It should just record the new value and let the getter make the conversion;i agree that the setter does not appear to be useful at all"

from question  

What is the setter doing in this code? ES6: Use getters and setters to Control Access to an Object

"Keep in mind that getter setter cannot have the same name as properties that you set in the constructor;you will end up exceeding the maximum call-stack with infinite recursion when you try to use the setter to set that same property"

from question  

ES6 - declare a prototype method on a class with an import statement

"In that case flex internally calls the getter to make sure that the value to be set is not the existing value;if the current value of the property as returned by the getter is same as the value to be set the setter is not called"

from question  

Flex set function not getting called

"Another way around this is to not set the property value in the constructor but instead to define the property with a getter and a setter in fact in this case a setter is not needed as a read only value is helpful;as we are using a getter this is not a normal property and is not set in the constructor"

from question  

Typescript mixins with default property values (derived from new MyClass)

"I think the getter is a better place;if the setter is called first - well then the setter will set the property to whatever the setter is asked to do so and nobody cares what the previous value of the property was"

from question  

Lazy instantiation in Setter or getter?

"Getter should retrieve the value by their name and explicitly make type conversion;setter shouldn t care - qvariant will"

from question  

Options for program

"In other words you can always access attributes so the concept of getter setter functions isn t needed;you can use property though which acts like a way to implement a getter with an underlying value"

"I have a parent class that has a setter that returns queryfiltre value and a getter that is supposed to pass the queryfiltre value to my child class"

from question  

Python 3 : Getter is not returning the data it should be

"Adding getter wouldn t interfere with your goal to validate an item before it is added to the list;also if you wanted you could also add a setter that looks something like this so the items would still be validated"

from question  

Spring RestController: serialize private fields

"In c++ cli a trivial property is one where the getter setter is not declared;with a non-trivial property the getter setter are declared explicitly with syntax that s more like a normal method declaration than c# s property syntax"

"The setter is not called when we set the value this means that the value actually erase the property and this will no more work as intended;the getter is no more called when we access the value again"

from question  

Dynamically adding a property is not working as expected

"1 first you need to create one class to fill listview and the element of one class should be whatever you want to display in list item and declare one integer than generate getter and setter method for it like"

"Also i recommend using setter and getter and making your class variables private rather than making setter and getter public"

from question  

Inherting values friom one object to another

"Edit following up on the comments above this also means that the properties in the constructor always have to be initialized they can t be computed properties since you can t give they getter and setter that wouldn t use they backing field"

from question  

What are the implementation of default accessors in Kotlin

"A public field is not worse than a getter setter pair that does nothing except returning the field and assigning to the field"

from question  

Why use getters and setters/accessors?

State entity integrity

Example

from question  

Protecting sensitive entity data

"Hiding state behind getter and setter gives you more flexibility to change the internal representation of the class state without breaking other classes that uses the class state"

from question  

Java accessors/mutators - programming form

Others

Example

But then your setter is less restricted than your getter which is odd.

from question  

Why is internal protected not more restrictive than internal?

Yes as the other answers state the getter are the same;the options retain copy and assign determine how to generate setter but not the names even of those

from question  

Are getters the same for all properties in objective-c?

I noticed the plugin had a setter but not a getter equivalent for the value of the editor;this is odd because the normal jquery pattern for plugins that create content with a value is to have the getter be an overloaded paramater-less version of the setter

from question  

Jquery Text editor

It is abstract in composition so i can override it in the children now i can add override the method in the track which takes it as a parameter and finally i make the album whose duration is the sum of the tracks it works as intended but i do not understand why i cannot simply use since in kotlin properties are nothing more than getter and setter i m thinking about the getduration in composition

from question  

Override getters in Kotlin?

The jit may even be able to recognize that the same register can be used for both purposes so if using such a getter makes code more readable that s a substantial argument in favor;unfortunately the inability of struct members to indicate whether or not struct members modify the underlying structure makes the underlying structure impossible to use the same approach for an indexed property setter

from question  

Getter property with arguments

If we put we filter in between these calls either in getter or setter setter is more efficient as it is called only when filters change we modify original filtered list with we filter and return our filter back through the getter

from question  

Primefaces custom filter in datatable

If we re just going to cast to the expected type we could use a dictionary of getter with the property name as the key would look like this to store the getter for a property propertyinfo discovered by reflection storing setter is more complicated

from question  

How to put all delegate methods into a dictionary?

So i think before following the convention of getter and setter the convention of getter is more important to follow the convention of variable naming

from question  

How to name getter/setter in Android project

The second getter is fragile the second getter will crash if somebody access s the object s title and then releases the object so the first is generally preferable even if marginally slower;the first setter is more efficient and will work even in situations where an autorelease pool doesn t exist so it s preferable

from question  

Which of these memory management techniques is better in what situations?

Or maybe a getter is more complex than just getting the value of a variable maybe it does some calculations;if you didn t have to use a setter and could just access the variable directly some developer might miss the fact some developer re supposed to use a setter for the above reasons which would obviously create issues

from question  

Reasoning behind Object Oriented Access Specifiers

I prefer having setter getter

from question  

Calling methods directly from a list filled with objectsA from objectB in python 3.7

So i recommend using getter and setter unless you have good reasons not to do so

from question  

Argument passing standardization

This way is better than having getter and setter in base of performance not to have reduntant code of two methods getter and setter

from question  

How to detect if a variable has changed?

Using annotated pojos with minimal getter and no setter is much more oo restoring encapsulation and with the possibility of immutability

from question  

What is a JavaBean exactly?

If you use reflector to look at the implementation of control.visible its getter does this;however its setter is much more complicated

from question  

Assignment statements not working

How do i safely call setter after getter chain eg foo.getx .gety .setz ...

The .css getter does not retrieve .style propeties it retrieves getcomputedstyle or .currentstyle in ie;so it is not symmetric with the .css setter which sets .style properties on the element

from question  

JavaScript Change Row Color Dynamically

Note that the test bean has a very special design as the getter returns a more general type number than the setter requests integer

from question  

Introspector.getBeanInfo, setters with property subclasses and Java 8

If the calculation is expensive or the getter is executed more often than the setter for the changeable properties playername by far it can be an optimization to change the property inside the class into a read-write property and set the value every time the changeable properties are changed

from question  

Updating a class with readonly properties in Objective-C

Now if this logic was in a viewmodel then i think the getter aspect is a little more forgivable expected

from question  

Logic in get part of property. Good practice?

For example if car has the color property it s acceptable to let clients observe it using a getter;if some client needs the ability to recolor a car the class can provide a setter recolor is more clear name though

from question  

Allen Holub wrote "You should never use get/set functions", is he correct?

As far as i know there is no way to use the old prototyping methodology for getter setter infact i believe the grand total of internal flex sdk classes that use any type of prototyping is 0;in any case getter setter aren t available in the prototype-hacking game

from question  

Add setter in a prototype in Flex

Getter should not be chainable because they need to return the referenced value;setter can be chainable

from question  

Basic chaining method is returning object of class error

Here i d recommend either putting the logic to calculate the volume on the getter and using only that method or having the getter call volume in case you need the latter in another part of the cylinder class;your setter methods aren t doing the validation because you re not calling them at all

from question  

Java getters and setters not working

So first yes there is a plugin for knockout that uses getter and setter but a plugin for knockout that uses getter and setter only works in newer browsers

from question  

Property definition is method definition when using knockout

In any case the getter is solved easily enough by using # instead of;the setter is more problematic however

from question  

How should I point to a record field in case of extensible object types?

Your getter setter doesn t follow standard java bean naming conventions and thus spring is not able to find getter for coursecode;getter should be getcoursecode not getcoursecode

from question  

Display of list of items in thymeleaf always gives error

El accesses properties by getter not directly by the field;if your setter is named setemail then your getter is likely named getemail so the property name is really email not email

from question  

Problem accesing email property with help of Expression Language/JSTL

If you are using jmsserializer with fosrestbundle the serializer usually accesses the values of your object using reflection so the getter aren t touched;you can however set the access type for the property or all of the properties in the object to the public method getter setter using the access_type setting

from question  

How can I use a DataTransformer transform with the FosRestBundle view layer

An alternative method to access the child component as early as possible is to associate the contentchild decorator to a getter setter property and to set the child flag in the setter see this stackblitz for a demo;please note that the private variable _child and the getter are not needed to set the flag

from question  

Host component changing behavior of child component

Well the getter are just fine since one really has to see the contents of the cart and the number of items in the cart;the setter are not fine

from question  

Java Encapsulation with arrays

Some pieces of code also use the getter setter specifically and not the fields so making sure your fields have getter setter is a good practice overall;for example apache beanutils.copybean will not copy a bean if getter setter are not set

from question  

Basic about function in OOP Java

Generally getter are not doing any alloc or init for you;your setter is a little closer and i assume this was for a property declared as retain

from question  

Setters and Getters on ARC environment

Using getter and setter gives you more control over the validity of your objects giving you the option of testing values that are set to ensure that getter and setter are reasonable etc

from question  

Difference between myClassInstance.property and myClassInsance.getProperty()?

The getter is not always simply return foo sometimes you will want to initialise other objects or perform logging;similarly the setter provides a neat mechanism for validating the new value attempting to be assigned to the variable

from question  

Modeling bank account balance

Yes it s more typing but with getter and setter users can easily see what properties getter and setter users can get and set plus getter and setter are ide s auto-complete friendly

from question  

Constructor versus too freaking many gets and sets

The problem here is likely related to your ability to check if getter setter were actually generated;if your ide tells you getter setter not generated - the ide might be wrong

from question  

How to use lombok.Data annotation in a Spring Boot application?

Replacing the getter with a macro is straightforward;replacing the setter is a bit trickier since you need to return the correct value

from question  

What is the meaning of "#define setId(ptr, value) ((ptr)->id = (value), 0)

Next time you re tediously implementing a getter consider what the caller will do with the data and whether you can just provide that functionality directly;properties encourage mutable state through setter which makes a program less parallelizable

from question  

Why will there be no native properties in Java 7?

If you have data that needs to be retrieved but under no circumstances should ever be changed use a getter but not a setter;if you have data that needs to be set for internal purposes and should never be publicly exposed and cannot be set at instantiation use a setter but not a getter setter presumably prevents a second call affecting the internal property

from question  

How to avoid getters and setters

The code in the setter is far more interesting than the getter should it not take precedence and be defined first

from question  

Why define the getter before the setter (coding convention)

The correct getter should be getbmdc and not getbmdc as it is in your code now;the correct model class should look like this the setter are not required are always optional because if there is no setter for a json property the firebase client will set the value directly onto the field

from question  

Firebase Read getter setter

So just store the title so that the getter is able to return it correctly;your setter does not set anything

from question  

Databinding activity does not update value when property has changed

A team which feels more comfortable with setter getter won t kill the project but you ll have to see a team which feels more comfortable with setter getter every day

from question  

Is POJO anti Object Orientation (OO)?

The setter complexity can be higher than the getter and thus validate a unit-test

from question  

Should unit tests be written for getter and setters?

The dbkey property getter is virtual in the il because it is in an interface;the setter is not virtual because it is not part of the interface but part of the concrete class

from question  

Why is this property Getter virtual?

The getter makes sure that the variables relation is loaded then returns the first value with a matching key;the setter is a little more complicated because we want to update an existing uservariable model if one exists and create one if it doesn t and in either case save the change in the relation but not the db

from question  

Laravel Eloquent 5.1 update related model efficiently

Will generate a setter named setstatuslabel and a getter statuslabel and a _statuslabel;there will be no variable named statuslabel when you use self and . syntax you are really calling the setter getter and not accessing the variable directly
