# ACE\_Event\_Tuple(3)

An ACE\_Event\_Handler and its associated ACE\_HANDLE.

## NAME

ACE\_Event\_Tuple -  An ACE\_Event\_Handler and its associated ACE\_HANDLE.

## SYNOPSIS

```
#include <ace/Select_Reactor_Base.h>
class ACE_Event_Tuple
{
  public:
    ACE_Event_Tuple (void);
    ACE_Event_Tuple (ACE_Event_Handler *eh, ACE_HANDLE h);
    ~ACE_Event_Tuple (void);
    int operator== (const ACE_Event_Tuple &rhs) const;
    int operator!= (const ACE_Event_Tuple &rhs) const;
    ACE_HANDLE handle_;
    ACE_Event_Handler* event_handler_;
};
```

## DESCRIPTION

One ACE\_Event\_Handler is registered for one or more ACE\_HANDLE, in some points this information must be stored explicitly. This structure provides a lightweight mechanism to do so.

## PUBLIC MEMBERS

```
ACE_Event_Tuple (void);
```

```
ACE_Event_Tuple (ACE_Event_Handler *eh, ACE_HANDLE h);
```

```
~ACE_Event_Tuple (void);
```

```
int operator== (const ACE_Event_Tuple &rhs) const;
```

Equality operator.

```
int operator!= (const ACE_Event_Tuple &rhs) const;
```

Inequality operator.

```
ACE_HANDLE handle_;
```

```
ACE_Event_Handler* event_handler_;
```
