isMatch

public abstract int isMatch(char[] buffer,
                            int pos,
                            int bufferStart,
                            int bufferEnd)

Deprecated.

Returns the number of matching characters, zero for no match.

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.

Parameters:

buffer - the text content to match against, do not change

pos - the starting position for the match, valid for buffer

bufferStart - the first active index in the buffer, valid for buffer

bufferEnd - the end index (exclusive) of the active buffer, valid for buffer

Returns:

the number of matching characters, zero for no match

isMatch

public int isMatch(char[] buffer,
                   int pos)

Deprecated.

Returns the number of matching characters, zero for no match.

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 matching code may check one character or many. It may check characters preceding pos as well as those after.

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.

Parameters:

buffer - the text content to match against, do not change

pos - the starting position for the match, valid for buffer

Returns:

the number of matching characters, zero for no match
