Method Detail

getJavaType

public java.lang.Class getJavaType()
Accessor for the Java type represented here.

Specified by:
getJavaType in class JavaTypeMapping
Returns:
The java type

insertPostProcessing

public void insertPostProcessing(ObjectProvider op)
Description copied from interface: MappingCallbacks
Hook so that we can handle any post-processing on the insert of a particular field. For example with Oracle we need to insert "EMPTY_CLOB" and then immediately after do a SELECT of it and update the contents of the CLOB/BLOB.

Specified by:
insertPostProcessing in interface MappingCallbacks
Parameters:
op - ObjectProvider

postInsert

public void postInsert(ObjectProvider sm)
Method to be called after the insert of the owner class element.

Specified by:
postInsert in interface MappingCallbacks
Parameters:
sm - StateManager of the owner

postUpdate

public void postUpdate(ObjectProvider sm)
Method to be called after any update of the owner class element.

Specified by:
postUpdate in interface MappingCallbacks
Parameters:
sm - StateManager of the owner

preDelete

public void preDelete(ObjectProvider sm)
Method to be called before any delete of the owner class element.

Specified by:
