acceptChildren(ExpressionVisitor visitor)
Visits the children of this
Expression. |
JPQLQueryBNF |
findQueryBNF(Expression expression)
Retrieves the
JPQLQueryBNF that represents the fragment of this Expression
that was used when parsing the given Expression. |
abstract java.lang.String |
getEncapsulatedExpressionQueryBNFId()
Returns the BNF used to parse the encapsulated expression.
|
Expression |
getExpression()
Returns the
Expression that is encapsulated within parenthesis. |
boolean |
hasEncapsulatedExpression()
Determines whether something was parsed after the left parenthesis.
|
boolean |
hasExpression()
Determines whether the encapsulated expression of the query was parsed.
|
void |
setExpression(AbstractExpression expression)
Manually sets the encapsulated
Expression to become the given one. |

Expression. This method can be used to optimize traversing
the children since a new list is not created every time Expression.children() is called.
This does not traverse the Expression sub-hierarchy, use a subclass of
AbstractTraverseChildrenVisitor in order to traverse the entire sub-hierarchy.
