    • isLeftOperation

      public boolean isLeftOperation()
      Description copied from interface: InfixOperator
      Defines the bind-direction of the operator. That direction defines, in which direction a sequence of equal operators is resolved.
      Returns:
      true, if the operation is left-binding, false if right-binding
    • isAssociative

      public boolean isAssociative()
      Defines, whether the operation is associative. For associative operations, the evaluation order does not matter, if the operation appears more than once in an expression, and therefore we can optimize them a lot better than non-associative operations (ie. merge constant parts and precompute them once).
      Returns:
      true, if the operation is associative, false otherwise
