Object |
compute(EvalContext context)
Evaluates the expression.
|

computeContextDependent()
Returns true if the root expression or any of the
predicates or the path steps are context dependent.

Object |
computeValue(EvalContext context)
Evaluates the expression.
|
protected Object |
expressionPath(EvalContext evalContext,
boolean firstMatch)
Walks an expression path (a path that starts with an expression)
|
Expression |
getExpression()
Get the expression.
|
Expression[] |
getPredicates()
Predicates are the expressions in brackets that may follow
the root expression of the path.
