Protected Member Functions

InverseComparator ()

Default constructor (necessary for the PortableObject interface).

Construct a InverseComparator.

Constructor & Destructor Documentation

InverseComparator ( Comparator::View vComparator ) [protected]

Construct a InverseComparator.

Parameters:

vComparator

the comparator whose results are inverted by this Comparator

Member Function Documentation

virtual int32_t compare	(	Object::View	vO1,
		Object::View	vO2
	)			const `[virtual]`

Use the wrapped Comparator to compare the two arguments for order and negate the result.

Parameters:

	vO1	the first object to be compared
	vO2	the second object to be compared

Returns:: a positive integer, zero, or a negative integer as the first argument is less than, equal to, or greater than the second

Exceptions:

ClassCastException

if the arguments' types prevent them from being compared by this Comparator.
