Deserialization

Deserialization is the process by which an object is recreated from its serialized state.

Serializable

Serialization is the process of converting a data structure or object state into a format that can be stored



Property setter getter

Example

"Recently i had the same issue using jackson-annotation 2.9.0 and lombok 1.18.2 this is what worked for me so basically adding the annotation means that the property may only be written for deserialization using setter but will not be read on serializable using getter"

from question  

@JsonIgnore with @Getter Annotation

"If the taskproperty class is decorated with datacontract attribute and with datamember attribute for each property the deserialization is much faster than when it is decorated with serializable attribute"

from question  

Why DataContract is faster than Serializable?

Complex easy

Example

"And deserialization is not more complex"

from question  

How to (de)serialize an EnumMap using Jackson and default typing?

"Serializable is easy but we have to deal with complex data structure implementations std string std map for example that play with allocated buffers;deserialization is more complex and you need to rebuild your object with all its members plus references to vtables ."

from question  

C++ JSON Serialization

Field bean value

Example

"Output is 0 and 10 0 because y is transient field it s not saved on bean serializable so upon deserialization it gets default value witch is 0 for int;10 is because z is static field thats mean it is not wired with instance serializable also doesn t erase it"

from question  

Serialization of Objects (java)

"Output is 10 because your object is in memory serializable doesn t erase transient fields it s just ignore them on serializable;output is 0 and 10 0 because y is transient field it s not saved on bean serializable so upon deserialization it gets default value witch is 0 for int"

from question  

Serialization of Objects (java)

Constructor package default

Example

"I think the default constructor is only necessary for deserialization never used a package for deserialization;serializable shouldn t need it"

from question  

Dart serializing immutable objects

"Serializable shouldn t need it;the default constructor is redundant because if the deserialization package needs a default constructor it obviously attempts to create an instance using the default constructor to afterwards set the field values which can t work with final fields"

from question  

Dart serializing immutable objects

"Java serializable was an old mechanism create decade before annotation;i guess that is why default serializable deserialization does not handle problem properly"

from question  

Class annotation causes ClassNotFound exception

Example

"The serializable seems quicker but deserialization much slower and the app is doing more deserializing than serializing"

from question  

XML vs Binary performance for Serialization/Deserialization

"The problem occurs when a serializable is slower then the next request s deserialization"

from question  

Vaadin with Spring and Redis loads previous UI state on slow environment

Harder self-made notice

Example

"Deserialization is harder than serializable"

from question  

Not knowing a type before deserializing

"I wold not bother with self-made serializable;notice that designing deserialization is harder than serialization..."

from question  

C/C++: Should serialization methods be class members?

Control process better

Example

"Side note check-out the json.net serializable which gives more options and better control over the deserialization process"

from question  

Serializer ignores properties that use another serialized property

"This gives you much better control over the serializable deserialization process and makes your class simpler with less boilerplate code"

from question  

What is the best way to generalize typed setters and getters?

"You ll need to implement serializable to have java handle the serializable or externalizable if you need more control over the deserialization process"

from question  

Non-serializable object error while working on Memcache

Others

Example

You might need a different view on deserialization and not just on serializable and that would be a jackson 2.0 feature - supported by spring 3.2 and backported into spring 3.1;using a view on serializable only is a feature since jackson 1.4

from question  

Can I ignore just a setter w/ Jackson & Spring?

The other is that while datacontractjsonserializer writes the local offset during serializable it doesn t use it properly during deserialization;it just assumes that if any offset is provided that the time should be local - even if the computer doing the deserialization has a completely different offset

Compare DateTime as a string into a LINQ to Entities doesn't recognize DateTime.parse(string)

Serializable deserialization becomes a bigger bottleneck when you scale out to a session server or use sql server to manage session state

from question  

Asp.net: Individual Session Variables vs Object Saved in Session

Have you considered creating an object structure for these files and serializing these files java object serializable and deserialization is much faster than parsing an xml this is again considering that these 500 or so xml files don t get modified between reads

from question  

Reading files from memory instead of disk

If you are worried about instantiating too many serializable you can always keep them in a dictionary keyed by type;deserialization is harder as you have to know the type of object first - if you can t get the caller to tell you what type to expect you will need to read the data before you try deserializing to determine the type

from question  

XmlSerializer: "The type 'Type' may not be used in this context"

I have rolled back the project to the initial state without classes map or custom serializable and changed the struct type to class type and it worked;in resume this exception error is related to structs deserialization not with interfaces deserialization

from question  

Deserialize object as an interface with MongoDB C# Driver

See the serializable check where the check is called and where deserialization happens in a non-local cluster;i believe that local mode clusters only test serializable not deserialization

from question  

Custom deserializer does not get called apache storm

1 there is a special case though when you can register only an abstract class for the purposes of serializable deserialization not for kryo.copy though;this case is when your serializable is the same for all subclasses and during deserialization you can decide which subclass to return based on the data

from question  

Do you need to register all implementations of an interface with Kryo?

Looks like yaml serializable doesn t like it;i used deserialization with specified type as you mentioned and this is what i get

from question  

How to convert JSON to YAML using YamlDotNet

You could also go through serializable form deserialization which is also less risky and handles more situations the code there uses a slightly different format though so you ll probably have to adapt it

from question  

Convert array to different type

Also i do not know which serializable deserialization method is more suitable for such a use case

from question  

What is the most efficient way of sharing a Julia object with C++?

You need to find the balance in serializable and deserialization performance speed ease of working with the data size of files number of files and management of files and ability to use external libraries;when it comes to file foramts and serializable binary is normally faser than json which is normally faster than xml

from question  

Loading an xml file with different view per viewmodel?

Using the same code for serializable and deserialization is even more of a pain i cannot off hand figure out how

from question  

How to change const std::shared_ptr after first assignment?

The key here is using the serializable to write an anonymous object that includes only the desired properties;note that readjson is left unimplemented - i am assuming that deserialization is not required at this stage

from question  

Only serialize some specific properties of a class?

Of course since serializable is not the same as;deserialization i don t understand how this is an explanation for the

from question  

Why has gson does not allow serialization of java.lang.Class?

I also tried but that gives the error impl doesn t use types inside crate i could probably live without deserialization since serializable is more important at this point

from question  

How do I serialize or deserialize an Arc<T> in Serde?

Also due to deserialization of the data it will take more memory than the serializable disk data

from question  

Spark: Data can't fit in memory and I want to avoid write it in disk, can I perform iterations with slices of the data to use only the memory?

Maybe serializable deserialization is the better way than save java code at the file

from question  

How can I read Class and objects name from File using Java Reflection?

I have an issue with serializable in c# .net where if i serializable in one stream multiple references to a same object these references are no longer equal after deserialization

from question  

How to maintain reference equality during serialization and deserialization

It comes with some serializable logic added via annotations to specify what should be ignored during serializable and what order should be applied during serializable and deserialization i want to change these annotations without having to creating my own class with all the other logic copied over

from question  

Override Json.NET annotation of base class in C#

I ve reworked it slightly so that the deserialization code looks more like the deserialization code serializable counterpart

from question  

XML - Can not deserialize after serialize

For serializable filtering properties blog entry should help;deserialization side has less support since it is more common to want to filter out stuff that is written
