| Modifier and Type | Method and Description |
|---|---|
void |
accept(ExpressionVisitor visitor)
Visits this
Expression by the given visitor. |
java.lang.String |
getParameterQueryBNFId(int index)
Returns the unique identifier of the
JPQLQueryBNF to be used to parse one of the
encapsulated expression at the given position. |
JPQLQueryBNF |
getQueryBNF()
Returns the BNF of this
Expression. |
protected boolean |
isThirdExpressionOptional()
Determines whether the third expression is an optional expression, which means a valid query
can have it or not.
