Constructor Detail

ComparableScalarSpacePredicate

protected ComparableScalarSpacePredicate()

Default constructor for Externalizable.

ComparableScalarSpacePredicate

protected ComparableScalarSpacePredicate(Comparable<?> expectedValue)

Creates a comparable scalar predicate using the specified expected value.

Parameters:

expectedValue - Expected value.

ComparableScalarSpacePredicate

protected ComparableScalarSpacePredicate(Comparable<?> expectedValue,
                                         Comparator<?> comparator)

Creates a comparable scalar predicate using the specified expected value and comparator.

Parameters:

expectedValue - Expected value.

comparator - Comparator to use while comparing.
