Method Details

acceptsStem

default boolean acceptsStem(String stem)

acceptsStem

boolean acceptsStem(char[] word,
 int offset,
 int length)

Returns:

whether the given word matches this condition as a stem with both "strip" and "affix" removed

uniqueKey

static String uniqueKey(AffixKind kind,
 String strip,
 String condition)

Returns:

a key used to deduplicate same condition+strip+kind triples. For trivial conditions that need no check, ALWAYS_TRUE_KEY is returned.

compile

static AffixCondition compile(AffixKind kind,
 String strip,
 String condition,
 String line)

Analyzes the given affix kind, strip and condition and returns an object able to efficiently check that condition.
