 ComparatorInputStream reactor,
 ArtifactComparator.ComparisonData data)

isEqualTextIngoreNewLine

public static boolean isEqualTextIngoreNewLine(byte[] baseline,
 byte[] reactor)

Tests if baseline and reactor contain equal text, if line-endings are ignored.

matches

public boolean matches(String nameOrExtension)

Description copied from interface: ContentsComparator

Check if this comparator matches the given name or extension

Specified by:

matches in interface ContentsComparator

Parameters:

nameOrExtension - the extension or name to match

Returns:

true if this comparator matches, false otherwise
