Imports
java.util.Iterator, com.ibm.icu.impl.StandardPlural, .StringSegment, .TextTrieMap, com.ibm.icu.text.DecimalFormatSymbols, com.ibm.icu.util.Currency, .Currency.CurrencyStringInfo
Matches a currency, either a custom currency or one from the data bundle. The class is called "combined" to emphasize that the currency string may come from one of multiple sources. Will match currency spacing either before or after the number depending on whether we are currently in the prefix or suffix. The implementation of this class is slightly different between J and C. See #13584 for a follow-up.

public boolean match(StringSegment segment, ParsedNumber result)

Implements com.ibm.icu.impl.number.parse.NumberParseMatcher.match.

Doc from com.ibm.icu.impl.number.parse.NumberParseMatcher.match.

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.

Parameters
segment:StringSegment

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:ParsedNumber

The data structure to store results if the match succeeds.

Returns:boolean

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

matchCurrencyback to summary
private boolean matchCurrency(StringSegment segment, ParsedNumber result)

Matches the currency string without concern for currency spacing.

postProcessback to summary
public void postProcess(ParsedNumber result)

Implements com.ibm.icu.impl.number.parse.NumberParseMatcher.postProcess.

Doc from com.ibm.icu.impl.number.parse.NumberParseMatcher.postProcess.

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.

Parameters
result:ParsedNumber

The data structure to store results.

smokeTestback to summary
public boolean smokeTest(StringSegment segment)

Implements com.ibm.icu.impl.number.parse.NumberParseMatcher.smokeTest.

Doc from com.ibm.icu.impl.number.parse.NumberParseMatcher.smokeTest.

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 method in order to correctly handle case folding.

Parameters
segment:StringSegment

The segment to check against.

Returns:boolean

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

Returns:String
