match	back to summary
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. Annotations @Override

match

back to summary

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.

public boolean match(StringSegment segment, ParsedNumber result, int exponentSign) Parameters exponentSign:int -1 means a negative exponent; +1 means a positive exponent; 0 means NO exponent. If -1 or +1, the number will be saved by scaling the pre-existing DecimalQuantity in the ParsedNumber. If 0, a new DecimalQuantity will be created to store the number.

postProcess	back 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. Annotations @Override

postProcess

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.

smokeTest	back 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. Annotations @Override
