# ACE\_Asynch\_Read\_Stream\_Result\_Impl(3)

Abstract base class for all the concrete implementation classes that provide different implementations for the ACE\_Asynch\_Read\_Stream::Result class.

## NAME

ACE\_Asynch\_Read\_Stream\_Result\_Impl -

Abstract base class for all the concrete implementation classes that provide different implementations for the ACE\_Asynch\_Read\_Stream::Result class.

## SYNOPSIS

```
class ACE_Asynch_Read_Stream_Result_Impl :
  public virtual ACE_Asynch_Result_Impl
{
  public:
    virtual ~ACE_Asynch_Read_Stream_Result_Impl (void);
    virtual u_long bytes_to_read (void) const = 0;
    virtual ACE_Message_Block &message_block (void) const = 0;
    virtual ACE_HANDLE handle (void) const = 0;
  protected:
    ACE_Asynch_Read_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

```
virtual ~ACE_Asynch_Read_Stream_Result_Impl (void);
```

```
virtual u_long bytes_to_read (void) const = 0;
```

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

```
virtual ACE_Message_Block &message_block (void) const = 0;
```

Message block which contains the read data.

```
virtual ACE_HANDLE handle (void) const = 0;
```

I/O handle used for reading.

## PROTECTED MEMBERS

```
ACE_Asynch_Read_Stream_Result_Impl (void);
```

Do-nothing constructor.
