getExpression
Description copied from interface:StateObject
Returns the actual parsed object if thisStateObject
representation of the JPQL query was created by parsing an existing JPQL query.- Specified by:
getExpression
in interfaceStateObject
- Overrides:
getExpression
in classCompoundExpressionStateObject
- Returns:
- The parsed object when a JPQL query is parsed and converted into a
StateObject
ornull
when the JPQL query is manually created (i.e. not from a string)
