Usage

From source file:Main.java

/**
 * Extract the UUID part from a MusicBrainz identifier.
 * //from  w w w .  j  a va 2s. c o  m
 * This function takes a MusicBrainz ID (an absolute URI) as the input
 * and returns the UUID part of the URI, thus turning it into a relative
 * URI. If <code>uriStr</code> is null or a relative URI, then it is
 * returned unchanged.
 * 
 * The <code>resType</code> parameter can be used for error checking.
 * Set it to 'artist', 'release', or 'track' to make sure 
 * <code>uriStr</code> is a syntactically valid MusicBrainz identifier
 * of the given resource type. If it isn't, an 
 * <code>IllegalArgumentException</code> exception is raised. This error
 * checking only works if <code>uriStr</code> is an absolute URI, of course.
 * 
 * Example:
 * >>>  MBUtils.extractUuid('http://musicbrainz.org/artist/c0b2500e-0cef-4130-869d-732b23ed9df5', 'artist')
 * 'c0b2500e-0cef-4130-869d-732b23ed9df5'
 * 
 * @param uriStr A string containing a MusicBrainz ID (an URI), or null
 * @param resType A string containing a resource type
 * @return A String containing a relative URI or null
 * @throws URISyntaxException
