expandWindow

public int expandWindow(java.nio.CharBuffer dst,
                        boolean skipParen,
                        boolean skipSpace)

Increase window size by 1 stride. If skipParen is true, and the immediately followed stride is a skippable, increase the window size to the end of the skippable. Copy new content to a buffer (not include skipped content).

Parameters:

dst - destination buffer for new content

skipParen - whether or not skip parenthesis if followed

skipSpace - whether or not copy space to the destination buffer

Returns:

number of characters copied
