    • 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.
    • equals

      public boolean equals(Object object)
      Overrides:
      equals in class 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.

      public String toString()
      Overrides:
