Method Detail

escape

public void escape(java.lang.String escapeChars,
                   java.lang.StringBuffer buf,
                   char next,
                   int pointer)

Do not perform any character escaping, except for '%', and ')'.

Here is the rationale. First, filename patterns do not include escape combinations such as \r or \n. Moreover, characters which have special meaning in logback parsers, such as '{', or '}' cannot be part of file names (so me thinks). The left parenthesis character has special meaning only if it is preceded by %. Thus, the only characters that needs escaping are '%' and ')'.

Note that this method assumes that it is called after the escape character has been consumed.
