# ACE\_Asynch\_Operation\_Impl(3)

Abstract base class for all the concrete implementation classes that provide different implementations for the ACE\_Asynch\_Operation.

## NAME

ACE\_Asynch\_Operation\_Impl -

Abstract base class for all the concrete implementation classes that provide different implementations for the ACE\_Asynch\_Operation.

## SYNOPSIS

```
class ACE_Asynch_Operation_Impl
{
  public:
    virtual ~ACE_Asynch_Operation_Impl (void);
    virtual int open (
        ACE_Handler &handler,
        ACE_HANDLE handle,
        const void *completion_key,
        ACE_Proactor *proactor
        ) = 0;
    virtual int cancel (void) = 0;
    virtual ACE_Proactor* proactor (void) const = 0;
  protected:
    ACE_Asynch_Operation_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.

## Access methods.

```
virtual ACE_Proactor* proactor (void) const = 0;
```

Return the underlying proactor.
