Modifier and Type | Method and Description |
---|---|
void |
accept(StateObjectVisitor visitor)
Visits this
StateObject by the given visitor . |
protected void |
addProblems(java.util.List<Problem> problems)
Adds to the given list the problems that were found with the current state of this
StateObject , which means there are validation issues. |
ObjectExpression |
getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
java.lang.String |
getIdentifier()
Returns the JPQL identifier of the expression represented by this
AbstractSingleEncapsulatedExpressionStateObject . |
void |
setExpression(ObjectExpression expression)
Keeps a reference of the
parsed object object, which should only be
done when this object is instantiated during the conversion of a parsed JPQL query into
StateObjects . |
