collectExpressionInfo
Collect expression info for a legacy handler submission. Namely the active part id and name, active shell name, active workbench window shell name and the active site name.- Overrides:
collectExpressionInfo
in classExpression
- Parameters:
info
- the expression information object used to collect the information- Since:
- 3.2
-
computeHashCode
protected int computeHashCode()Description copied from class:Expression
Method to compute the hash code for this object. The result returned from this method in cached in thefHashCode
field. 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:
computeHashCode
in classExpression
- Returns:
- a hash code for this object.
-
equals
-
evaluate
Evaluates this expression. This tests the three conditions against the current state of the application (as defined bycontext
). If a condition isnull
, then it matches any possible value (i.e., it is not tested at all).- Specified by:
evaluate
in classExpression
- Parameters:
context
- The context providing the current workbench state; must not benull
.- Returns:
EvaluationResult.TRUE
if the conditions all matches;EvaluationResult.FALSE
otherwise.
