C# Класс wpf_player.ObservableStream

This class extends memory stream to allow waiting state management and position change notify. Using the WaitForMore method, a event will be launched when the needed data has been read. Position Changed event will be launched when more data has been written on the stream: the maximum resolution for this events is 1024 byte; if the position changed for less than 1024 byte the event won't be raised.

Наследование: System.IO.MemoryStream

WaitForMore ( int how_many = 15000 ) : void	Sets the waiting state for the stream and sets the position waited.
Write ( byte buffer, int offset, int count ) : void	This method after the call of the base class implementation uses the launchEvent method to raise the right event See MSDN Reference for Memory Stream for Details.

Защищенные методы

Метод	Описание
OnPositionChanges ( EventArgs args ) : void	This method calls the event handler for the position changed event
OnWaitedPositionReached ( EventArgs args ) : void	This method calls the event handler for the waited position reached event

Приватные методы

Метод	Описание
launchEvent ( ) : void	This method is used to launch stream events. This performs check for waiting state and last launched position and raise the right event in the right moment.
