      • LegacyHandlerSubmissionExpression

        public LegacyHandlerSubmissionExpression​(String activePartId,
                                                 Shell activeShell,
                                                 IWorkbenchPartSite activeSite)
        Constructs a new instance of LegacyHandlerSubmissionExpression
        Parameters:
        activePartId - The part identifier to match with the active part; null if it will match any active part.
        activeShell - The shell to match with the active shell; null if it will match any active shell.
        activeSite - The site to match with the active site; null if 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:
        collectExpressionInfo in class Expression
        Parameters:
        info - the expression information object used to collect the information

      • 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 the fHashCode field. If the value returned from the method equals Expression.HASH_CODE_NOT_COMPUTED (e.g. -1) then the value is incremented by one.

        This default implementation calls super.hashCode()

        Overrides:
        computeHashCode in class Expression
        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 by context). If a condition is null, then it matches any possible value (i.e., it is not tested at all).
        Specified by:
        evaluate in class Expression
        Parameters:
        context - The context providing the current workbench state; must not be null.
        Returns:
        EvaluationResult.TRUE if the conditions all matches; EvaluationResult.FALSE otherwise.
