Method Detail

getFilesystem

DOMFileSystemSync getFilesystem()

getFullPath

String getFullPath()

isDirectory

boolean isDirectory()

isFile

boolean isFile()

getName

String getName()

copyTo

EntrySync copyTo(DirectoryEntrySync parent,
               String name)

Copy an entry to a different location on the file system. You cannot copy an entry inside itself if it is a directory nor can you copy it into its parent if a name different from its current one isn't provided. Directory copies are always recursive—that is, they copy all contents of the directory.

void vopyTo (
  (in DirectoryEntry parent, optional DOMString newName, optional EntryCallback successCallback, optional ErrorCallback errorCallback);
);

Parameter

parent

The directory to which to move the entry.

newName

The new name of the entry. Defaults to the entry's current name if unspecified.

successCallback

A callback that is called with the entry for the new object.

errorCallback

A callback that is called when errors happen.

Returns

void

getMetadata

Metadata getMetadata()

Look up metadata about this entry.

void getMetada (
  in MetadataCallback ErrorCallback
);

Parameter

successCallback

A callback that is called with the time of the last modification.

errorCallback

A callback that is called when errors happen.

Returns

void

getParent

EntrySync getParent()

Look up the parent DirectoryEntry containing this entry. If this entry is the root of its filesystem, its parent is itself.

void getParent (
  (in EntryCallback successCallback, optional ErrorCallback errorCallback);
);

Parameter

parent

The directory to which to move the entry.

newName

The new name of the entry. Defaults to the entry's current name if unspecified.

successCellback

A callback that is called with the entry for the new object.

errorCallback

A callback that is called when errors happen.

Returns

void

moveTo

EntrySync moveTo(DirectoryEntrySync parent,
               String name)

Move an entry to a different location on the file system. You cannot do the following:

• move a directory inside itself or to any child at any depth;
• move an entry into its parent if a name different from its current one isn't provided;
• move a file to a path occupied by a directory;
• move a directory to a path occupied by a file;
• move any element to a path occupied by a directory which is not empty.

Moving a file over an existing file replaces that existing file. A move of a directory on top of an existing empty directory replaces that directory.

void moveTo (
  (in DirectoryEntry parent, optional DOMString newName, optional EntryCallback successCallback, optional ErrorCallback errorCallback);
);

Parameter

parent

The directory to which to move the entry.

newName

The new name of the entry. Defaults to the entry's current name if unspecified.

successCallback

A callback that is called with the entry for the new object.

errorCallback

A callback that is called when errors happen.

Returns

void

remove

void remove()

Deletes a file or directory. You cannot delete an empty directory or the root directory of a filesystem.

void remove (
  (in VoidCallback successCallback, optional ErrorCallback errorCallback);
);

Parameter

successCallback

A callback that is called with the entry for the new object.

errorCallback

A callback that is called when errors happen.

Returns

void

toURL

String toURL()

Returns a URL that can be used to identify this entry. It has no specific expiration. Bcause it describes a location on disk, it is valid for as long as that location exists. Users can supply mimeType to simulate the optional mime-type header associated with HTTP downloads.

DOMString toURL (
  (in optional DOMString mimeType);
);

Parameter

mimeType

For a FileEntry, the mime type to be used to interpret the file, when loaded through this URL.

Returns

DOMString
