Class SeriesMatcher

java.lang.Object

org.graalvm.shadowed.com.ibm.icu.impl.number.parse.SeriesMatcher

All Implemented Interfaces:

NumberParseMatcher

Direct Known Subclasses:

AffixPatternMatcher

public class SeriesMatcher
extends Object
implements NumberParseMatcher

Composes a number of matchers, running one after another. Matches the input string only if all of the matchers in the series succeed. Performs greedy matches within the context of the series.

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.

toString

public String toString()

Overrides:

toString in class Object
