Method Detail

execute

public void execute()
             throws org.apache.maven.plugin.MojoExecutionException,
                    org.apache.maven.plugin.MojoFailureException

Specified by:

execute in interface org.apache.maven.plugin.Mojo

Throws:

org.apache.maven.plugin.MojoExecutionException

org.apache.maven.plugin.MojoFailureException

getLoadingClassLoader

public 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(javassist.CtClass classDescriptor)

Description copied from interface: EnhancementContext

Does the given class descriptor represent a 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(javassist.CtClass 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.

doDirtyCheckingInline

public boolean doDirtyCheckingInline(javassist.CtClass 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.

hasLazyLoadableAttributes

public boolean hasLazyLoadableAttributes(javassist.CtClass 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

isLazyLoadable

public boolean isLazyLoadable(javassist.CtField 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.

isPersistentField

public boolean isPersistentField(javassist.CtField 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.

isMappedCollection

public boolean isMappedCollection(javassist.CtField field)

Specified by:

isMappedCollection in interface EnhancementContext

Parameters:

field - the field to check

Returns:

true if the field is mapped

order

public javassist.CtField[] order(javassist.CtField[] persistentFields)

Description copied from interface: EnhancementContext

For fields which are persistent (according to EnhancementContext.isPersistentField(javassist.CtField)), 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.
