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.
