Method Detail

getName

public String getName()

Overrides:

getName in class File

getPath

public String getPath()

Overrides:

getPath in class File

Returns:

String containing path of file.

length

public long length()

Overrides:

length in class File

getChunkSize

public int getChunkSize()

createNewFile

public boolean createNewFile()
                      throws IOException

Overrides:

Throws:

IOException

delete

public boolean delete()

Overrides:

delete in class File

isChildOf

protected static boolean isChildOf(String parent,
                                   String child)

Returns:

Throws:
