Открытые методы

Метод Описание
ConfigureAlignment ( long startPosition ) : void

Configure the natural alignment of the data.
ConfigureAlignment ( long startPosition, int alignment ) : void

Configure the natural alignment of the data.
Dispose ( ) : void

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
GetBlock ( BlockArguments args ) : void

Gets a block for the following Io session.
ReadBlock ( long position, IntPtr &pointer, int &validLength ) : void

Reads from the underlying stream the requested set of data. This function is more user friendly than calling GetBlock().
