-
getSingleJdbcMapping
public JdbcMapping getSingleJdbcMapping()
- Specified by:
getSingleJdbcMapping
in interfaceJdbcMappingContainer
-
bindParameterValue
public void bindParameterValue(PreparedStatement statement, int startPosition, JdbcParameterBindings jdbcParamBindings, ExecutionContext executionContext) throws SQLException

-
forEachJdbcType
public int forEachJdbcType(int offset, IndexedConsumer<JdbcMapping> action)
Description copied from interface:JdbcMappingContainer

forEachJdbcType
in interfaceJdbcMappingContainer
-
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.
- Specified by:
disassemble
in interfaceBindable

addToCacheKey
public void addToCacheKey(MutableCacheKeyBuilder cacheKey, Object value, SharedSessionContractImplementor session)
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 interfaceBindable
- Parameters:
cacheKey
- the MutableCacheKey used to add the disassembled value and the hashCodevalue
- the value to disassemblesession
- the SharedSessionContractImplementor
-
forEachDisassembledJdbcValue
public <X,Y> int forEachDisassembledJdbcValue(Object value, int offset, X x, Y y, Bindable.JdbcValuesBiConsumer<X,Y> valuesConsumer, SharedSessionContractImplementor session)
Description copied from interface:Bindable
LikeBindable.forEachDisassembledJdbcValue(Object, Object, Object, JdbcValuesBiConsumer, SharedSessionContractImplementor)
, but additionally receives an offset by which the selectionIndex is incremented when callingBindable.JdbcValuesBiConsumer.consume(int, Object, Object, Object, JdbcMapping)
.- Specified by:
forEachDisassembledJdbcValue
in interfaceBindable
-
forEachJdbcValue
public <X,Y> int forEachJdbcValue(Object value, int offset, X x, Y y, Bindable.JdbcValuesBiConsumer<X,Y> valuesConsumer, SharedSessionContractImplementor session)
Description copied from interface:Bindable
Visit each constituent JDBC value extracted from the entity instance itself. Short-hand form of callingBindable.disassemble(java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor)
and piping its result toBindable.forEachDisassembledJdbcValue(Object, int, JdbcValuesConsumer, SharedSessionContractImplementor)
