disassemble
public Object disassemble(Object value, SharedSessionContractImplementor session)
Description copied from interface:Bindable
Breaks down a value ofJ
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 theBindable
for thePerson
entity to disassemble. Given aPerson
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.
