Method Detail

getJavaType

public Class getJavaType()

Accessor for the Java type represented here.

Specified by:

getJavaType in class JavaTypeMapping

Returns:

The java type

insertPostProcessing

public void insertPostProcessing(org.datanucleus.state.ObjectProvider ownerOP)

Description copied from class: JavaTypeMapping

Perform any INSERT post processing as required by constituent ColumnMappings. TODO Not yet utilised, see RDBMS-14

Specified by:

insertPostProcessing in interface MappingCallbacks

Overrides:

insertPostProcessing in class JavaTypeMapping

Parameters:

ownerOP - ObjectProvider of the object with this mapping

postInsert

public void postInsert(org.datanucleus.state.ObjectProvider ownerOP)

Method to be called after the insert of the owner class element.

Specified by:

postInsert in interface MappingCallbacks

Parameters:

ownerOP - ObjectProvider of the owner

postUpdate

public void postUpdate(org.datanucleus.state.ObjectProvider ownerOP)

Method to be called after any update of the owner class element. This method could be called in two situations

• Update a collection field of an object by replacing the collection with a new collection, so UpdateRequest is called, which calls here
• Persist a new object, and it needed to wait til the element was inserted so goes into dirty state and then flush() triggers UpdateRequest, which comes here

Specified by:

postUpdate in interface MappingCallbacks

Parameters:

ownerOP - ObjectProvider of the owner

preDelete

public void preDelete(org.datanucleus.state.ObjectProvider ownerOP)

Method to be called before any delete of the owner class element.

Specified by:

preDelete in interface MappingCallbacks

Parameters:

ownerOP - ObjectProvider of the owner
