Throws:

IOException

copyTree

public static void copyTree(File src,
 File dst,
 Path prefix,
 PathFilter filter)
                     throws IOException

Throws:

IOException

copyTree

protected static void copyTree(int rootIndex,
 File src,
 File dst,
 Path prefix,
 PathFilter filter)
                        throws IOException

Throws:

IOException

getFilePathFromUrl

public static String getFilePathFromUrl(URL url)

Decodes an URL path so that is can be processed as a filename later.

Parameters:

url - the Url to be processed.

Returns:

the decoded path.

getFileFromURL

public static File getFileFromURL(URL url)

getParentPath

public static String getParentPath(String path)

getFileName

public static String getFileName(String path)

getFileExtension

public static String getFileExtension(String path)

getFileNameNoExt

getResourcePathFromContext

public static String getResourcePathFromContext(String resource)

Retrieves the total path of a resource from the Thread Context.

Parameters:

resource - the resource name to be retrieved.

Returns:

the decoded path or null if the resource doesn't exist.

getResourceFileFromContext

public static File getResourceFileFromContext(String resource)

findFiles

public static File[] findFiles(File root,
 String pattern,
 boolean recurse)

collectFiles

public static void collectFiles(File root,
 FileNamePattern pattern,
 List<File> result)

collectFiles
