LegacyHandlerSubmissionExpression
public LegacyHandlerSubmissionExpression(String activePartId, Shell activeShell, IWorkbenchPartSite activeSite)
Constructs a new instance ofLegacyHandlerSubmissionExpression- Parameters:
activePartId- The part identifier to match with the active part;nullif it will match any active part.activeShell- The shell to match with the active shell;nullif it will match any active shell.activeSite- The site to match with the active site;nullif it will match any active site.

collectExpressionInfo
public void collectExpressionInfo(ExpressionInfo info)
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:
collectExpressionInfoin classExpression- Parameters:
info- the expression information object used to collect the information- Since:
- 3.2
-
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 classExpression- Returns:
- a hash code for this object.
-
evaluate
public EvaluationResult evaluate(IEvaluationContext context)
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:
evaluatein classExpression- Parameters:
context- The context providing the current workbench state; must not benull.- Returns:
EvaluationResult.TRUEif the conditions all matches;EvaluationResult.FALSEotherwise.
