int isMatch(char[] buffer, int pos, int bufferStart, int bufferEnd)
This method is called to check for a match. The parameter pos
represents the current position to be
checked in the string buffer
(a character array which must not be changed). The API guarantees that
pos
is a valid index for buffer
.
The character array may be larger than the active area to be matched. Only values in the buffer between the specified indices may be accessed.
The matching code may check one character or many. It may check characters preceding pos
as well as
those after, so long as no checks exceed the bounds specified.
It must return zero for no match, or a positive number if a match was found. The number indicates the number of characters that matched.
buffer
- the text content to match against, do not changepos
- the starting position for the match, valid for bufferbufferStart
- the first active index in the buffer, valid for bufferbufferEnd
- the end index (exclusive) of the active buffer, valid for bufferCopyright © 2014–2018 The Apache Software Foundation. All rights reserved.
