Method Detail
-
accept
public void accept(StateObjectVisitor visitor)
Visits thisStateObjectby the givenvisitor.- Parameters:
visitor- Thevisitorto visit this object
-
getExpression
public SubtractionExpression getExpression()
Returns the actual parsed object if thisStateObjectrepresentation of the JPQL query was created by parsing an existing JPQL query.- Specified by:
getExpressionin interfaceStateObject- Overrides:
getExpressionin classArithmeticExpressionStateObject- Returns:
- The parsed object when a JPQL query is parsed and converted into a
StateObjectornullwhen the JPQL query is manually created (i.e. not from a string)
-
getIdentifier
public java.lang.String getIdentifier()
Returns the identifier joining the twoStateObjects.- Specified by:
getIdentifierin classCompoundExpressionStateObject- Returns:
- The JPQL identifier join two expressions
-
setExpression
public void setExpression(SubtractionExpression expression)
Keeps a reference of theparsed objectobject, which should only be done when this object is instantiated during the conversion of a parsed JPQL query intoStateObjects.- Parameters:
expression- Theparsed objectrepresenting a subtraction expression
