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

Description copied from interface: Bindable

Add to the MutableCacheKey the values obtained disassembling the value and the hasCode generated from the disassembled value.

Specified by:

addToCacheKey in interface Bindable

Parameters:

cacheKey - the MutableCacheKey used to add the disassembled value and the hashCode

value - the value to disassemble

session - the SharedSessionContractImplementor

forEachDisassembledJdbcValue

public <X,Y> int forEachDisassembledJdbcValue(Object value,
                                                    int offset,
                                                    X x,

                                                    SharedSessionContractImplementor session)

Description copied from interface: Bindable

Like Bindable.forEachDisassembledJdbcValue(Object, Object, Object, JdbcValuesBiConsumer, SharedSessionContractImplementor), but additionally receives an offset by which the selectionIndex is incremented when calling Bindable.JdbcValuesBiConsumer.consume(int, Object, Object, Object, JdbcMapping).

Specified by:

forEachDisassembledJdbcValue in interface Bindable

forEachJdbcValue

public <X,Y> int forEachJdbcValue(Object value,
                                        int offset,

Visit each constituent JDBC value extracted from the entity instance itself.
