Extract the values of the component properties from the given component instance without access to the session.

An optional operation

Specified by:

getPropertyValues in interface CompositeType

Parameters:

component - The component instance

Returns:

The property values

isAnyType

public boolean isAnyType()

Description copied from interface: Type

Return true if the implementation is castable to AnyType. Shortcut for type instanceof AnyType.

An AnyType is additionally an AssociationType; so if this method returns true, then Type.isAssociationType() should also return true.

Specified by:

isAnyType in interface Type

Overrides:

isAnyType in class AbstractType

Returns:

True if this type is also an AnyType implementor; false otherwise.

isAssociationType

public boolean isAssociationType()

Description copied from interface: Type

Return true if the implementation is castable to AssociationType. This does not necessarily imply that the type actually represents an association. Shortcut for type instanceof AssociationType.

Specified by:

isAssociationType in interface Type

Overrides:

isAssociationType in class AbstractType

Returns:

True if this type is also an AssociationType implementor; false otherwise.

isComponentType

public boolean isComponentType()

Description copied from interface: Type

Return true if the implementation is castable to CompositeType. Shortcut for type instanceof CompositeType.

A component type may own collections or associations and hence must provide certain extra functionality.

Specified by:

isComponentType in interface Type

Overrides:

isComponentType in class AbstractType

Returns:

True if this type is also a CompositeType implementor; false otherwise.

isEmbedded

public boolean isEmbedded()

Description copied from interface: CompositeType

Is this component embedded? "embedded" indicates that the component is "virtual", that its properties are "flattened" onto its owner

Specified by:

isEmbedded in interface CompositeType

Returns:

True if this component is embedded; false otherwise.

isMutable

public boolean isMutable()

Description copied from interface: Type

Are objects of this type mutable with respect to the referencing object? Entities and collections are considered immutable because they manage their own internal state.

Specified by:

isMutable in interface Type

Returns:

boolean

deepCopy

public Object deepCopy(Object value,
                       SessionFactoryImplementor factory)

Description copied from interface: Type

Return a deep copy of the persistent state, stopping at entities and at collections.

Specified by:

deepCopy in interface Type

Parameters:

value - The value to be copied

factory - The session factory

Returns:

The deep copy

compare

public int compare(Object x,
                   Object y)

Description copied from interface: Type

Perform a Comparator-style comparison of the given values.

Specified by:

compare in interface Type

Overrides:

compare in class AbstractType

Parameters:

x - The first value

y - The second value

Returns:

The comparison result.

See Also:

Comparator.compare(Object, Object)

compare

public int compare(Object x,
                   Object y,
                   SessionFactoryImplementor factory)

Specified by:

compare in interface Type

isSame

public boolean isSame(Object x,
                      Object y)
               throws HibernateException

Description copied from interface: Type

Compare two instances of the class mapped by this type for persistence "equality", that is, equality of persistent state, taking a shortcut for entity references.

For most types this should boil down to an equality comparison of the given values, and it's reasonable to simply delegate to Type.isEqual(Object, Object). But for associations the semantics are a bit different.

Specified by:

isSame in interface Type

Overrides:

isSame in class AbstractType

Parameters:

x - The first value

y - The second value

Returns:

True if there are considered the same (see discussion above).

Throws:

HibernateException - A problem occurred performing the comparison

isModified

public boolean isModified(Object old,
                          Object current,
                          boolean[] checkable,
                          SharedSessionContractImplementor session)
                   throws HibernateException

Description copied from interface: Type

Has the value been modified compared to the current database state? The difference between this and the Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor) methods is that here we need to account for "partially" built values. This is really only an issue with association types. For most type implementations it is enough to simply delegate to Type.isDirty(java.lang.Object, java.lang.Object, org.hibernate.engine.spi.SharedSessionContractImplementor).

Specified by:

isModified in interface Type

Overrides:

isModified in class AbstractType

Parameters:

old - the database state, in a "hydrated" form, with identifiers unresolved

current - the current state of the object

checkable - which columns are actually checkable

session - The session from which the request originated.

Returns:

true if the field has been modified

Throws:

HibernateException - A problem occurred performing the checking

toColumnNullness

public boolean[] toColumnNullness(Object value,
                                  Mapping mapping)

Description copied from interface: Type

Given an instance of the type, return an array of boolean values indicating which mapped columns would be null.

Specified by:

Parameters:

value - an instance of the type

mapping - The mapping abstraction

Returns:

array indicating column nullness for a value instance

                       boolean[] checkable,
                       SharedSessionContractImplementor session)
                throws HibernateException

public int getColumnSpan(Mapping session)

Description copied from interface: Type

How many columns are used to persist this type?

Always the same as getSqlTypCodes(mapping).length.

Specified by:

getColumnSpan in interface Type

Parameters:

session - The mapping object :/

Returns:

The number of columns

nullSafeSet
