Method Details
-
getJavaType
Accessor for the Java type represented here.- Specified by:
getJavaType
in classJavaTypeMapping
- Returns:
- The java type
-
containerIsStoredInSingleColumn
protected boolean containerIsStoredInSingleColumn()Convenience method to return if the array is stored in the owning table as a column. Overrides the superclass since arrays can be stored in a single column also when the no join is specified and the array is of a primitive/wrapper type.- Overrides:
containerIsStoredInSingleColumn
in classAbstractContainerMapping
- Returns:
- Whether it is stored in a single column in the main table.
-
postInsert
public void postInsert(org.datanucleus.state.DNStateManager ownerSM) Description copied from interface:MappingCallbacks
Method called after the insert of the object so that additional operations can be performed if necessary.- Specified by:
postInsert
in interfaceMappingCallbacks
- Parameters:
ownerSM
- StateManager of the owner
-
postFetch
public void postFetch(org.datanucleus.state.DNStateManager sm) Description copied from class:AbstractContainerMapping
Method to be called after any fetch of the owner class element.- Specified by:
postFetch
in interfaceMappingCallbacks
- Overrides:
postFetch
in classAbstractContainerMapping
- Parameters:
sm
- StateManager of the owner
-
postUpdate
public void postUpdate(org.datanucleus.state.DNStateManager ownerSM) Method to be called after any update of the owner class element. This method could be called in two situations- Update an array field of an object by replacing the array with a new array, 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 interfaceMappingCallbacks
- Parameters:
ownerSM
- StateManager of the owner
-
preDelete
public void preDelete(org.datanucleus.state.DNStateManager ownerSM) Description copied from interface:MappingCallbacks
Method called before the delete of objects, so that additional operations can be performed if necessary.- Specified by:
preDelete
in interfaceMappingCallbacks
- Parameters:
ownerSM
- StateManager of the owner
