ComparisonConstraint(object, bool, bool, bool, string)

Initializes a new instance of the ComparisonConstraint class.

protected ComparisonConstraint(object value, bool lessComparisonResult, bool equalComparisonResult, bool greaterComparisonResult, string predicate)

Parameters

value object

The value against which to make a comparison.

lessComparisonResult bool

if set to true less succeeds.

equalComparisonResult bool

if set to true equal succeeds.

greaterComparisonResult bool

if set to true greater succeeds.

predicate string

String used in describing the constraint.

Fields

equalComparisonResult

if true, equal returns success
