computeHashCode
protected int computeHashCode()Description copied from class:ExpressionMethod to compute the hash code for this object. The result returned from this method in cached in thefHashCodefield. If the value returned from the method equalsExpression.HASH_CODE_NOT_COMPUTED(e.g.-1) then the value is incremented by one.This default implementation calls
super.hashCode()- Overrides:
computeHashCodein classCompositeExpression- Returns:
- a hash code for this object.
-
evaluate
Description copied from class:ExpressionEvaluates this expression.- Specified by:
evaluatein classExpression- Parameters:
context- an evaluation context providing information like variable, name spaces, etc. necessary to evaluate this expression- Returns:
- the result of the expression evaluation
- Throws:
CoreException- if the evaluation failed. The concrete reason is defined by the subclass implementing this method
-
collectExpressionInfo
Description copied from class:ExpressionCollects information about this expression tree. This default implementation add the expression's type to the set of misbehaving expression types.- Overrides:
collectExpressionInfoin classCompositeExpression- Parameters:
info- the expression information object used to collect the information
-
toString
