Public Member Functions

virtual int32_t compare (Object::View vO1, Object::View vO2) const
 Use the wrapped Comparator to compare the two arguments for order and negate the result.
virtual int32_t compareEntries (QueryMap::Entry::View vEntry1, QueryMap::Entry::View vEntry2) const
 Compare two entries using the underlying comparator and negate the result.
virtual bool equals (Object::View v) const

Static Public Member Functions

getInstance ()
 An instance of the InverseComparator.

Protected Member Functions

 InverseComparator ()
 Default constructor (necessary for the PortableObject interface).
 InverseComparator (Comparator::View vComparator)
 Construct a InverseComparator.

Constructor & Destructor Documentation

InverseComparator ( Comparator::View  vComparator  )  [protected]

Construct a InverseComparator.

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.

vO1 the first object to be compared
vO2 the second object to be compared
a positive integer, zero, or a negative integer as the first argument is less than, equal to, or greater than the second
ClassCastException if the arguments' types prevent them from being compared by this Comparator.

Reimplemented from SafeComparator.
