  • Method Details

    • flip

      public ComparisonOperator flip()
      Description copied from class: ComparisonOperator
      Return the operator to use if this operation needs to be flipped due to the CohQL statement having the literal on the left hand side. For example if the statement was "2 == foo" this would need to be flipped to put the literal on the right so giving the statement "foo == 2" and the flipped operator is still ==. But for another example such as "2 >= foo" flipping this give the statement "foo <= 2" so the operator has changed from >= to <=
      Specified by:
      flip in class ComparisonOperator
      Returns:
      the operator to use if this operation needs to be flipped due to the CohQL statement having the literal on the left hand side.

    • makeFilter

      public ComparisonFilter makeFilter(Object oLeft, Object oRight)
      Description copied from class: BaseOperator
      Create a Filter for this BaseOperator using the specified left and right values.

      Note: This method should be thread safe as operators are stored in a static map so may be called by multiple threads.

      Overrides:
      makeFilter in class BaseOperator<ComparisonFilter>
      Parameters:
      oLeft - the left value to use to build a Filter
      oRight - the right value to use to build a Filter
      Returns:
      a Filter representing this operation

    • addToTokenTable

      public void addToTokenTable(TokenTable tokenTable)
      Description copied from class: BaseOperator
      Add this operator to the given TokenTable. This typically means adding this operator using its symbol and also adding any aliases.
      Specified by:
      addToTokenTable in class BaseOperator<ComparisonFilter>
      Parameters:
      tokenTable - the TokenTable to add this operator to
