Method Detail

globPathAsRegex

public static String globPathAsRegex(String pathWithGlobs)

Converts the provided path containing glob characters * and ** into a regular expression. The definition matches that of the GlobbingPathFilter with the addition that this conversion also supports sub-paths which do not start with a /.

The rules are:

• leading ** matches /foo and bar
• leading /** matches /foo but not bar
• intermittent ** matches zero or any number of path elements
• trailing ** matches anything not ending with a /
• single * matches anything except /
• ? is not a special character
• anything not a star is wrapped into \Q...\E pairs

Parameters:

pathWithGlobs - path that can contain * and **

Returns:

a regular expression
