Method Detail

getRangeCount

public int getRangeCount()

Description copied from interface: IRangeComparator

Returns the number of comparable entities.

Specified by:

getRangeCount in interface IRangeComparator

Returns:

the number of comparable entities

rangesEqual

public boolean rangesEqual(int idx,
                  IRangeComparator rc2,
                  int idx2)

Description copied from interface: IRangeComparator

Returns whether the comparable entity given by the first index matches an entity specified by the other IRangeComparator and index.

Specified by:

rangesEqual in interface IRangeComparator

Parameters:

idx - the index of the comparable entity within this IRangeComparator

rc2 - the IRangeComparator to compare this with

idx2 - the index of the comparable entity within the other IRangeComparator

Returns:

true if the comparable entities are equal

skipRangeComparison

public boolean skipRangeComparison(int length,
                          int maxLength,
                          IRangeComparator other)

Description copied from interface: IRangeComparator

Returns whether a comparison should be skipped because it would be too costly (or lengthy).

Specified by:

skipRangeComparison in interface IRangeComparator

Parameters:

length - a number on which to base the decision whether to return true or false

maxLength - another number on which to base the decision whether to return true or false

other - the other IRangeComparator to compare with

Returns:

true to avoid a too lengthy range comparison

getItem

public EventSequence getItem(int idx)
