[jira] [Updated] (IGNITE-15978) Support binary HANLDEs by BinaryObjectBuilder

     [ https://issues.apache.org/jira/browse/IGNITE-15978?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vladimir Ermakov updated IGNITE-15978:
--------------------------------------
    Description: 
We have to support binary HANLDEs by BinaryObjectBuilder.

Now, the binary object is created by marshaling the java object may contain filed that is represented by the HANDLE (reference) to the other member of the upper object.e.g.

 

{{class MyClass \{
   List<Value> lst0;
   List<Value> lst1;
}
MyClass var = new MyClass();
var.lst0 = ...;
var.lst1 = lst0; // Will be serialized as the HANDLE with offset that refers to the lst0}}

 

But the same layout of the binary object cannot be built by BinaryObjectBuilder.e.g.:

BinaryObjectBuilder bob = builder("MyClass");
List<Value> lst = ...;
bob.setField("lst0", lst);
bob.setField("lst1", lst);
BinaryObject bo = bob.build(); // Binary object will not contain HANDLE. The collections will be marshaled independently,
.
