accept
public void accept(StateObjectVisitor visitor)
Visits thisStateObject
by the givenvisitor
.- Parameters:
visitor
- Thevisitor
to visit this object
-
getExpression

- Returns:
- The JPQL identifier that is shown before the left parenthesis
-
setExpression
public void setExpression(UpperExpression expression)
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 anUPPER
expression
