Detailed Description

template<typename Data>
class ecl::Topic< Data >

Stores publisher and subscriber lists to a uniquely string identified topic.

This is not for direct use, its the storage container for the sigslots manager.

Definition at line 45 of file topic.hpp.


Member Typedef Documentation

template<typename Data>
typedef std::set<SigSlot<Data>*> ecl::Topic< Data >::Subscribers

A list of subscribers (slots) to a given topic.

Definition at line 50 of file topic.hpp.


Constructor & Destructor Documentation

template<typename Data>
ecl::Topic< Data >::Topic ( const std::string &  name) [inline]

Uniquely construct with the specified name.

Parameters:
name: name of the topic.

Definition at line 56 of file topic.hpp.


Member Function Documentation

template<typename Data>
void ecl::Topic< Data >::addPublisher ( SigSlot< Data > *  sigslot) [inline]

Add a publisher.

Parameters:
sigslot: the sigslot to add.

Definition at line 75 of file topic.hpp.

template<typename Data>
void ecl::Topic< Data >::addSubscriber ( SigSlot< Data > *  sigslot) [inline]

Add a subscriber.

Parameters:
sigslot: the sigslot to add.

Definition at line 68 of file topic.hpp.

template<typename Data>
void ecl::Topic< Data >::disconnect ( SigSlot< Data > *  sigslot) [inline]

Disconnect a sigslot.

This parses both publishers and subscribers looking for the sigslot to connect. Could be a bit heavy doing it this way, but its convenient.

Parameters:
sigslot: the sigslot to disconnect.

Definition at line 86 of file topic.hpp.

template<typename Data>
bool ecl::Topic< Data >::empty ( ) const [inline]

Checks to see if there is no publishers/subscribers.

This is used to delete the topic (by the manager) if it is empty.

Returns:
bool : empty (true) or not (false).

Definition at line 102 of file topic.hpp.

template<typename Data>
const Subscribers* ecl::Topic< Data >::subscribers ( ) const [inline]

List of subscribers (listeners) to a topic.

Returns:
Subscribers : handle to the list.

Definition at line 62 of file topic.hpp.

) [friend]
