Constructor Detail

ComparisonOperation

public ComparisonOperation(java.lang.String name)

Default constructor with default behavior for > < operators. For >= <= == or !=, you need to set ifOneNaNOperand and ifTwoNaNOperands.

Parameters:

name - WarpScript function name

ComparisonOperation

public ComparisonOperation(java.lang.String name,
                           boolean trueIfOneNaNOperand,
                           boolean trueIfTwoNaNOperands)

Parameters:

name - WarpsScript function name

trueIfOneNaNOperand - set it for != comparison

trueIfTwoNaNOperands - set it for == or <= or >= comparison
