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 owni,
                           IRangeComparator otherComp,
                           int otheri)

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:

owni - the index of the comparable entity within this IRangeComparator

otherComp - the IRangeComparator to compare this with

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

Returns:

true if the comparable entities are equal

skipRangeComparison

public boolean skipRangeComparison(int arg0,
                                   int arg1,
                                   IRangeComparator arg2)

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:

arg0 - a number on which to base the decision whether to return true or false

arg1 - another number on which to base the decision whether to return true or false

arg2 - the other IRangeComparator to compare with

Returns:

true to avoid a too lengthy range comparison

getMatchRatio

public double getMatchRatio(TextOnlyComparator other,
                            org.eclipse.core.runtime.IProgressMonitor progressMonitor)
