open method
- {FileMode mode = FileMode.read}
override
Opens the file for random access operations.
Returns a Future<RandomAccessFile> that completes with the opened
random access file. RandomAccessFiles must be closed using the
RandomAccessFile.close method.
Files can be opened in three modes:
-
FileMode.read: open the file for reading.
-
FileMode.write: open the file for both reading and writing and truncate the file to length zero. If the file does not exist the file is created.
-
FileMode.append: same as FileMode.write except that the file is not truncated.
Throws a FileSystemException if the operation fails.
Implementation
@override
Future<RandomAccessFile> open({
FileMode mode = FileMode.read,
}) =>
delegate.open(mode: mode);
