C# Class System.IO.NetFxToWinRtStreamAdapter

An wrapper for a managed stream that implements all WinRT stream operations. This class must not implement any WinRT stream interfaces directly. We never create instances of this class directly; instead we use classes defined in the region Interface adapters to implement WinRT ifaces and create instances of those types. See comment in that region for technical details.

Private Methods

Method	Description
CanApplyReadMemoryStreamOptimization ( Stream stream ) : bool
Create ( Stream stream ) : NetFxToWinRtStreamAdapter
DetermineStreamReadOptimization ( Stream stream ) : StreamReadOperationOptimization
EnsureNotDisposed ( ) : Stream
IDisposable ( ) : void	Implements IDisposable.Dispose (IClosable.Close in WinRT)
NetFxToWinRtStreamAdapter ( Stream stream, StreamReadOperationOptimization readOptimization ) : System.Diagnostics
SetWonInitializationRace ( ) : void	We keep tables for mappings between managed and WinRT streams to make sure to always return the same adapter for a given underlying stream. However, in order to avoid global locks on those tables, several instances of this type may be created and then can race to be entered into the appropriate map table. All except for the winning instances will be thrown away. However, we must ensure that when the losers are finalized, they do not dispose the underlying stream. To ensure that, we must call this method on the winner to notify it that it is safe to dispose the underlying stream.
