          String outputField)

Construct a Comparison object used to configure a field comparison operator.

Parameters:

leftField - the name of the left hand side field to compare

rightField - the name of the right hand side field to compare

op - the comparison operation to perform

outputField - the name of the field resulting from the comparison

Comparison

public Comparison(String field,
          ComparisonType op,
          String outputField)
