EntrySync

Methods

Code DirectoryReaderSync createReader() #

Creates a new DirectoryReader to read entries from this Directory.

void getMetada ();

Returns

DirectoryReader

from MDN

DirectoryReaderSync createReader();

Code DirectoryEntrySync getDirectory(String path, Object flags) #

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

from MDN

DirectoryEntrySync getDirectory(String path, Object flags);

Code FileEntrySync getFile(String path, Object flags) #

Creates or looks up a file.

void moveTo (
  (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, getFile must fail.
If create is true, the path doesn't exist, and no other error occurs, getFile must create it as a zero-length file and return a corresponding FileEntry.
If create is not true and the path doesn't exist, getFile must fail.
If create is not true and the path exists, but is a directory, getFile must fail.
Otherwise, if no other error occurs, getFile must return a FileEntry corresponding to path.

successCallback: A callback that is called to return the file selected or created.
errorCallback: A callback that is called when errors happen.

Returns

void

from MDN

FileEntrySync getFile(String path, Object flags);

Code void removeRecursively() #

Deletes a directory and all of its contents, if any. If you are deleting a directory that contains a file that cannot be removed, some of the contents of the directory might be deleted. You cannot delete the root directory of a file system.

DOMString toURL (
  (in VoidCallback successCallback, optional ErrorCallback errorCallback);
);

Parameter

successCallback: A callback that is called to return the DirectoryEntry selected or created.
errorCallback: A callback that is called when errors happen.
