Detailed Description

This class implements connection management for signal and slot objects. It makes sure that all connections where this object is involved are closed on destruction. Deriving classes can overload Connectable::opened and Connectable::closed to tune connection managenment.

Constructor & Destructor Documentation

Connectable

(

)

Creates an empty Connectable.

virtual ~Connectable

(

)

[virtual]

When a Connectable object is destroyed, it closes all its connections automatically.

(

const Connectable &

c

)

Member Function Documentation

virtual bool opened

(

const Connection &

c

)

[virtual]

This function is called when a new Connection involving this object is opened. The default implementation adds the connection to a list, so the destructor can close it.

Parameters:

c

Connection being opened

Returns:

True if the Connection was accepted

Reimplemented in EventLoop, and EventSource.

virtual void closed

(

const Connection &

c

)

[virtual]

This function is called when a new Connection involving this object is closed. The default implementation removes the connection from its list of connections.

Parameters:

c

Connection being opened

Reimplemented in EventLoop, and EventSource.

Connectable& operator=

(

const Connectable &

rhs

)

[protected]

Connectables can be copy constructed if the derived class provides a public copy constructor. Copying a Connectable will not change its connections.
