If the file does is not a directory, then this method returns null. Otherwise an array of File objects is returned, one for each file or directory in the directory. Pathnames denoting the directory itself and the directory's parent directory are not included in the result. Each resulting abstract pathname is constructed from this abstract pathname using the File(File, String) constructor. Therefore if this pathname is absolute then each resulting pathname is absolute; if this pathname is relative then each resulting pathname will be relative to the same directory.

There is no guarantee that the name strings in the resulting array will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order.

Returns:

An array of abstract pathnames denoting the files and directories in the directory denoted by this abstract pathname. The array will be empty if the directory is empty. Returns null if this abstract pathname does not denote a directory, or if an I/O error occurs.

Returns an array of abstract pathnames denoting the files in the specified directory.

Parameters:: directoryObj - directory object; filter - The filename filter to use, or null for none.
Returns:: An array of abstract pathnames denoting the files and directories in the directory denoted by this abstract pathname. The array will be empty if the directory is empty. Returns null if this abstract pathname does not denote a directory, or if an I/O error occurs.
See Also:: If the file does is not a directory, then this method returns null. Otherwise an array of File objects is returned, one for each file or directory in the directory. Pathnames denoting the directory itself and the directory's parent directory are not included in the result. Each resulting abstract pathname is constructed from this abstract pathname using the {@link #File(java.io.File, java.lang.String) File(File, String)} constructor. Therefore if this pathname is absolute then each resulting pathname is absolute; if this pathname is relative then each resulting pathname will be relative to the same directory.
There is no guarantee that the name strings in the resulting array will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order.

Returns an array of abstract pathnames denoting the requested files in the specified directory and all subdirectories. Entries for the directories themselves are not included in the result. Each resulting abstract pathname is constructed from the given abstract pathname using the 'File' constructor. Therefore if the given pathname is absolute then each resulting pathname is absolute; if the given pathname is relative then each resulting pathname will be relative to the same directory. There is no guarantee that the name strings in the resulting array will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order. Note that the given filename filter must accept all directory entries (i.e., an 'IstiFileFilter' with 'setAcceptDirectories(true)').

Parameters:: dirFileObj - directory object to use.; filterObj - filename filter to use, or null for none.
