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 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:

ownerOP - ObjectProvider

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.

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
