Method Detail

requireStart

boolean requireStart()

Returns true iff the start of the transparent region was hit by the search engine in the last match operation performed by this matcher; this can only happen if the pattern starts with a boundary matcher or contains lookbehind constructs.

When this method returns true, then it is possible that more input before the capturing region would have changed the result of the last search.

hitStart

boolean hitStart()

Returns true iff the start of input was hit by the search engine in the last match operation performed by this matcher; this can only happen if the pattern starts with a boundary matcher or contains lookbehind constructs.

When this method returns true, then it is possible that more input before the capturing region would have changed the result of the last search.
