COMPARATOR

public static final Comparator<AffixMatcher> COMPARATOR

Comparator for two AffixMatcher instances which prioritizes longer prefixes followed by longer suffixes, ensuring that the longest prefix/suffix pair is always chosen.

Method Detail

createMatchers

public static void createMatchers(AffixPatternProvider patternInfo,
                                  NumberParserImpl output,
                                  AffixTokenMatcherFactory factory,
                                  IgnorablesMatcher ignorables,
                                  int parseFlags)

match

public boolean match(StringSegment segment,
                     ParsedNumber result)

Description copied from interface: NumberParseMatcher

Runs this matcher starting at the beginning of the given StringSegment. If this matcher finds something interesting in the StringSegment, it should update the offset of the StringSegment corresponding to how many chars were matched.

Specified by:

match in interface NumberParseMatcher

Parameters:

segment - The StringSegment to match against. Matches always start at the beginning of the segment. The segment is guaranteed to contain at least one char.

result - The data structure to store results if the match succeeds.

Returns:

Whether this matcher thinks there may be more interesting chars beyond the end of the string segment.

smokeTest

public boolean smokeTest(StringSegment segment)

Description copied from interface: NumberParseMatcher

Performs a fast "smoke check" for whether or not this matcher could possibly match against the given string segment. The test should be as fast as possible but also as restrictive as possible. For example, matchers can maintain a UnicodeSet of all code points that count possibly start a match. Matchers should use the StringSegment.startsWith(int) method in order to correctly handle case folding.

Specified by:

smokeTest in interface NumberParseMatcher

Parameters:

segment - The segment to check against.

Returns:

true if the matcher might be able to match against this segment; false if it definitely will not be able to match.

postProcess

public void postProcess(ParsedNumber result)

Description copied from interface: NumberParseMatcher

Method called at the end of a parse, after all matchers have failed to consume any more chars. Allows a matcher to make final modifications to the result given the knowledge that no more matches are possible.

Specified by:

postProcess in interface NumberParseMatcher

Parameters:

result - The data structure to store results.

equals

public boolean equals(Object _other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
