Methods
Code DirectoryReader createReader() #
Creates a new DirectoryReader to read entries from this Directory.
void getMetada ();
Returns
DirectoryReader
DirectoryReader createReader();
Code void getDirectory(String path, [Object flags, EntryCallback successCallback, ErrorCallback errorCallback]) #
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.
Returns
void
void getDirectory(String path, [Object flags, EntryCallback successCallback, ErrorCallback errorCallback]);
Code void getFile(String path, [Object flags, EntryCallback successCallback, ErrorCallback errorCallback]) #
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
void getFile(String path, [Object flags, EntryCallback successCallback, ErrorCallback errorCallback]);
Code void removeRecursively(VoidCallback successCallback, [ErrorCallback errorCallback]) #
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.
Returns
void
void removeRecursively(VoidCallback successCallback, [ErrorCallback errorCallback]);
