Method Detail

createReader

DirectoryReader createReader()

Creates a new DirectoryReader to read entries from this Directory.

void getMetada ();

Returns

DirectoryReader

getDirectory

void getDirectory(String path)

Creates or looks up a directory.

void vopyTo (
  (in DOMString path, optional Flags options, optional EntryCallback successCallback, optional ErrorCallback errorCallback);
);

Parameter

path

Either an absolute path or a relative path from this DirectoryEntry to the file to be looked up or created. It is an error to attempt to create a file whose immediate parent does not yet exist.

options

• If create and exclusive are both true, and the path already exists, getDirectory must fail.
• If create is true, the path doesn't exist, and no other error occurs, getDirectory must create it as a zero-length file and return a corresponding getDirectory.
• If create is not true and the path doesn't exist, getDirectory must fail.
• If create is not true and the path exists, but is a directory, getDirectory must fail.
• Otherwise, if no other error occurs, getFile must return a getDirectory corresponding to path.

successCallback

A callback that is called to return the DirectoryEntry selected or created.

errorCallback

A callback that is called when errors happen.

Returns

void

getDirectory
