## NAME

ACE_Asynch_Write_Stream_Result_Impl -

Abstract base class for all the concrete implementation classes that provide different implementations for the ACE_Asynch_Write_Stream::Result.

## SYNOPSIS

    class ACE_Asynch_Write_Stream_Result_Impl :
      public virtual ACE_Asynch_Result_Impl
    {
      public:
        inline virtual ~ACE_Asynch_Write_Stream_Result_Impl ();
        virtual u_long bytes_to_write (void) const = 0;
        virtual ACE_Message_Block &message_block (void) const = 0;
        virtual ACE_HANDLE handle (void) const = 0;
      protected:
        ACE_Asynch_Write_Stream_Result_Impl (void);
    };

## DESCRIPTION

This class contains asbtract base classes for all the concrete implementation classes for the various asynchronous operations that are used with the Praoctor.

## PUBLIC MEMBERS

    inline virtual ~ACE_Asynch_Write_Stream_Result_Impl ();

    virtual u_long bytes_to_write (void) const = 0;

The number of bytes which were requested at the start of the asynchronous write.

    virtual ACE_Message_Block &message_block (void) const = 0;

Message block that contains the data to be written.

    virtual ACE_HANDLE handle (void) const = 0;

I/O handle used for writing.

## PROTECTED MEMBERS

    ACE_Asynch_Write_Stream_Result_Impl (void);

Do-nothing constructor.
