EnhancementContextWrapper

public EnhancementContextWrapper(EnhancementContext wrappedContext,
                                 java.lang.ClassLoader loadingClassloader)

Method Detail

getLoadingClassLoader

public java.lang.ClassLoader getLoadingClassLoader()

Description copied from interface: EnhancementContext

Obtain access to the ClassLoader that can be used to load Class references. In JPA SPI terms, this should be a "temporary class loader" as defined by PersistenceUnitInfo.getNewTempClassLoader()

Specified by:

getLoadingClassLoader in interface EnhancementContext

Returns:

The class loader that the enhancer can use.

isEntityClass

public boolean isEntityClass(UnloadedClass classDescriptor)

Description copied from interface: EnhancementContext

Does the given class descriptor represent an entity class?

Specified by:

isEntityClass in interface EnhancementContext

Parameters:

classDescriptor - The descriptor of the class to check.

Returns:

true if the class is an entity; false otherwise.

isCompositeClass

public boolean isCompositeClass(UnloadedClass classDescriptor)

Description copied from interface: EnhancementContext

Does the given class name represent an embeddable/component class?

Specified by:

isCompositeClass in interface EnhancementContext

Parameters:

classDescriptor - The descriptor of the class to check.

Returns:

true if the class is an embeddable/component; false otherwise.

isMappedSuperclassClass

public boolean isMappedSuperclassClass(UnloadedClass classDescriptor)

Description copied from interface: EnhancementContext

Does the given class name represent a MappedSuperclass class?

Specified by:

isMappedSuperclassClass in interface EnhancementContext

Parameters:

classDescriptor - The descriptor of the class to check.

Returns:

true if the class is a mapped super class; false otherwise.

doBiDirectionalAssociationManagement

public boolean doBiDirectionalAssociationManagement(UnloadedField field)

Description copied from interface: EnhancementContext

Should we manage association of bi-directional persistent attributes for this field?

Specified by:

doBiDirectionalAssociationManagement in interface EnhancementContext

Parameters:

field - The field to check.

Returns:

true indicates that the field is enhanced so that for bi-directional persistent fields the association is managed, i.e. the associations are automatically set; false indicates that the management is handled by the user.

doDirtyCheckingInline

public boolean doDirtyCheckingInline(UnloadedClass classDescriptor)

Description copied from interface: EnhancementContext

Should we in-line dirty checking for persistent attributes for this class?

Specified by:

doDirtyCheckingInline in interface EnhancementContext

Parameters:

classDescriptor - The descriptor of the class to check.

Returns:

true indicates that dirty checking should be in-lined within the entity; false indicates it should not. In-lined is more easily serializable and probably more performant.

doExtendedEnhancement

public boolean doExtendedEnhancement(UnloadedClass classDescriptor)

Description copied from interface: EnhancementContext

Should we enhance field access to entities from this class?

Specified by:

doExtendedEnhancement in interface EnhancementContext

Parameters:

classDescriptor - The descriptor of the class to check.

Returns:

true indicates that any direct access to fields of entities should be routed to the enhanced getter / setter method.

hasLazyLoadableAttributes

public boolean hasLazyLoadableAttributes(UnloadedClass classDescriptor)

Description copied from interface: EnhancementContext

Does the given class define any lazy loadable attributes?

Specified by:

hasLazyLoadableAttributes in interface EnhancementContext

Parameters:

classDescriptor - The class to check

Returns:

true/false

isPersistentField

public boolean isPersistentField(UnloadedField ctField)

Description copied from interface: EnhancementContext

Does the field represent persistent state? Persistent fields will be "enhanced".

may be better to perform basic checks in the caller (non-static, etc) and call out with just the Class name and field name...

Specified by:

isPersistentField in interface EnhancementContext

Parameters:

ctField - The field reference.

Returns:

true if the field is ; false otherwise.

order

public UnloadedField[] order(UnloadedField[] persistentFields)

Description copied from interface: EnhancementContext

For fields which are persistent (according to EnhancementContext.isPersistentField(org.hibernate.bytecode.enhance.spi.UnloadedField)), determine the corresponding ordering maintained within the Hibernate metamodel.

Specified by:

order in interface EnhancementContext

Parameters:

persistentFields - The persistent field references.

Returns:

The ordered references.

isLazyLoadable

public boolean isLazyLoadable(UnloadedField field)

Description copied from interface: EnhancementContext

Determine if a field is lazy loadable.

Specified by:

isLazyLoadable in interface EnhancementContext

Parameters:

field - The field to check

Returns:

true if the field is lazy loadable; false otherwise.

isMappedCollection

public boolean isMappedCollection(UnloadedField field)

Specified by:

isMappedCollection in interface EnhancementContext

Parameters:

field - the field to check

Returns:

true if the field is mapped
