disassemble

public Object disassemble(Object value,
 SharedSessionContractImplementor session)

Description copied from interface: Bindable

Breaks down a value of J into its simple pieces. E.g., an embedded value gets broken down into an array of its attribute state; a basic value converts to itself; etc.

Generally speaking, this is the form in which entity state is kept relative to a Session via EntityEntry.

 @Entity class Person {
     @Id Integer id;
     @Embedded Name name;
     int age;
 }

 @Embeddable class Name {
     String familiarName;
     String familyName;
 }
 

At the top level, we would want to disassemble a Person value, so we'd ask the Bindable for the Person entity to disassemble. Given a Person value:

 Person( id=1, name=Name( 'Steve', 'Ebersole' ), 28 )
 

this disassemble would result in a multidimensional array:

 [ ["Steve", "Ebersole"], 28 ]
 

Note that the identifier is not part of this disassembled state. Note also how the embedded value results in a sub-array.

Specified by:

disassemble in interface Bindable

Specified by:

disassemble in interface EntityValuedModelPart
