public class MqlComparisonNode
extends MqlBinaryOperator

We need to treat comparisons specially because: 1) a comparison with 'blabla' of an intEnum will be transformed into its int 2) a comparison to a '7charPointer' will be transformed into that value 3) a comparison to a parameter will determine the parameter type
