Method Details

toNormalizedPath

public static String toNormalizedPath(String aPath)

Normalizes the given path. Some implementations have problems with a beginning separator character. This method removes the beginning separator, also replaces all "/" to the valid separator and returns the result.

Parameters:

aPath - The path to be normalized

Returns:

The normalized path

getName

public static String getName(String aKey)

Gets the name portion from the provided key (the key without the path portion).

Parameters:

aKey - The key from which to get the name portion

Returns:

The name portion

getPath

public static String getPath(String aKey)

Gets the path portion from the provided key (the key without the name portion).

Parameters:

aKey - The key from which to get the path portion

Returns:

The path portion

toKey

public static String toKey(String aPath,
 String aName)

Creates a key from the given path portion and name portion.

Parameters:

aPath - The path to use

aName - The name to use

Returns:

The key

deleteFiles

public static void deleteFiles(FileSystem aFileSystem,
 String aPath,
 boolean isRecursively)

Deletes the entries found for the given path.

Parameters:

aFileSystem - the file system

aPath - The path where to look whether there are file (handle)s or not.

isRecursively - When true all children of that path are examined as well.

toTruncated

public static String toTruncated(String aPath)

Truncates any prefixed path separator as we assemble our new path with the according namespace in front.

Parameters:

aPath - The path to truncate.

Returns:

The truncated path, e.g. no prefixed path delimiters.

toNormalizedPath

public static String toNormalizedPath(String aPath,
 FileSystem aFileSystem)
                               throws IllegalPathException

Truncates any prefixed path separator as we assemble our new path with the according namespace in front. Test whether the given path may jail break from the name space. In case this "could" be the case, an IllegalPathException is thrown.

Parameters:

aPath - The path to be checked.

aFileSystem - The file system to use to get additional information.

Returns:

The truncated path.

Throws:

IllegalPathException - in case the path may jail break the name space.

toNormalizedKey

public static String toNormalizedKey(String aKey,
 FileSystem aFileSystem)
                              throws IllegalKeyException

Truncates any prefixed path separator as we assemble our new path with the according namespace in front. Test whether the given key may jail break from the name space. In case this "could" be the case, an IllegalKeyException is thrown.

Parameters:

aKey - The key to be checked.

aFileSystem - The file system to use to get additional information.

Returns:

The truncated key.

Throws:

IllegalKeyException - in case the key may jail break the name space.

toNormalizedName

public static String toNormalizedName(String aName,
 FileSystem aFileSystem)
                               throws IllegalNameException

Truncates any prefixed path separator as we assemble our new path with the according namespace in front. Test whether the given key may jail break from the name space. In case this "could" be the case, an IllegalKeyException is thrown.

Parameters:

aName - The key to be checked.

aFileSystem - The file system to use to get additional information.

Returns:

The truncated key.

Throws:

IllegalNameException - in case the name may jail break the name space.

toNormalizedFileHandle

public static FileHandle toNormalizedFileHandle(FileHandle aFileHandle,
 FileSystem aFileSystem)
                                         throws IllegalFileException

Test whether the given key may jail break from the name space. In case this "could" be the case, an IllegalKeyException is thrown.

Parameters:

aFileHandle - The file handle to be checked.

aFileSystem - The file system to use to get additional information.

Returns:

the file handle

Throws:

IllegalFileException - in case the key may jail break the name space.
