Interface IndirectComparator

All Known Implementing Classes:

IndirectComparator.AscendingDoubleComparator, IndirectComparator.AscendingFloatComparator, IndirectComparator.AscendingIntComparator, IndirectComparator.AscendingShortComparator, IndirectComparator.DelegatingComparator, IndirectComparator.DescendingDoubleComparator, IndirectComparator.DescendingFloatComparator, IndirectComparator.DescendingIntComparator, IndirectComparator.DescendingShortComparator

public interface IndirectComparator

Compare objects at two given indices and return the result of their comparison consistent with IndirectComparator.AscendingIntComparator's contract.

Beware of the return (int - int) idiom, it is usually broken if arbitrary numbers can appear on input. Use regular comparison operations - they are very fast anyway.
