the text to be matched
text, int[]
on input, the index into text at which to begin matching. On output, the limit of the matched text. The number of matched characters is the output value of offset minus the input value. Offset should always point to the HIGH SURROGATE (leading code unit) of a pair of surrogates, both on entry and upon return.
offset, int
the limit index of text to be matched. Greater than offset for a forward direction match, less than offset for a backward direction match. The last character to be considered for matching will be text.charAt(limit-1) in the forward direction or text.charAt(limit+1) in the backward direction.
limit, boolean
if true, then assume further characters may be inserted at limit and check for partial matching. Otherwise assume the text as given is complete.

public void addMatchSetTo(UnicodeSet toUnionTo)

Implements com.ibm.icu.text.UnicodeMatcher.addMatchSetTo.

Implementation of UnicodeMatcher API. Union the set of all characters that may be matched by this object into the given set.

Parameters
toUnionTo:UnicodeSet

the set into which to union the source characters

Returns:void

a reference to toUnionTo

public int matches(Replaceable text, int[] offset, int limit, boolean incremental)

Implements com.ibm.icu.text.UnicodeMatcher.matches.

Implement UnicodeMatcher API.

Parameters
text:Replaceable

Doc from com.ibm.icu.text.UnicodeMatcher.matches.

the text to be matched

offset:int[]

Doc from com.ibm.icu.text.UnicodeMatcher.matches.

on input, the index into text at which to begin matching. On output, the limit of the matched text. The number of matched characters is the output value of offset minus the input value. Offset should always point to the HIGH SURROGATE (leading code unit) of a pair of surrogates, both on entry and upon return.

limit:int

Doc from com.ibm.icu.text.UnicodeMatcher.matches.

the limit index of text to be matched. Greater than offset for a forward direction match, less than offset for a backward direction match. The last character to be considered for matching will be text.charAt(limit-1) in the forward direction or text.charAt(limit+1) in the backward direction.

incremental:boolean

if true, then assume further characters may be inserted at limit and check for partial matching. Otherwise assume the text as given is complete.

Returns:int

Doc from com.ibm.icu.text.UnicodeMatcher.matches.

a match degree value indicating a full match, a partial match, or a mismatch. If incremental is false then U_PARTIAL_MATCH should never be returned.
