i'not done messing with FileUtil :)
here's the problem:
catPath throws an ArrayIndexOutOfBoundsException if lookupPath
(the base path) does not contain any '/' char.
so, i've attached a replacement method.
the change in the new version are :
- no more ArrayIndexOutOfBoundsException, therefore support
of relative path is ok.
- output is normalized (wich makes the code significantly simplier,
but also often slower).
- always throws NullPointerException if any parameter is null.
/*
* addition to javadoc :
*
* - this method handles java/unix style path only (separator is '/').
* - it handles absolute and relative path.
* - returned path is normalized (as with method <code>normalize<code>).
*
* @see #normalize
* @throws NullPointerException if any parameter is null.
*/
public static String catPath( String lookupPath, final String path )
{
if (path == null)
throw new NullPointerException ("path is null.");
if (!lookupPath.endsWith ("/"))
{
int index = lookupPath.lastIndexOf ("/");
if (index < 0)
{
lookupPath = "";
}
else
{
lookupPath = lookupPath.substring (0, index+1);
}
}
return normalize (lookupPath + path);
}
