accept
Description copied from interface:StateObject
Visits thisStateObject
by the givenvisitor
.- Parameters:
visitor
- Thevisitor
to visit this object
-
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 classArithmeticExpressionStateObject
- 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)
-
getIdentifier

Returns the identifier joining the twoStateObjects
.- Specified by:
getIdentifier
in classCompoundExpressionStateObject
- Returns:
- The JPQL identifier join two expressions
-
setExpression
Keeps a reference of theparsed object
object, which should only be done when this object is instantiated during the conversion of a parsed JPQL query intoStateObjects
.- Parameters:
expression
- Theparsed object
representing a division expression
