Detailed Description

template<typename Data = Void>
class ecl::SigSlot< Data >

Not for direct use, provides the power behind both signals and slots.

This is the workhorse for both signals and slots, providing the implementation for all the functions necessary by both types of frontends.

Member Typedef Documentation

◆ PublicationMap

template<typename Data = Void>
typedef std::map<std::string, const Subscribers*> ecl::SigSlot< Data >::PublicationMap

Stores publishing topics and their followers.

Definition at line 66 of file sigslot.hpp.

◆ Subscribers

template<typename Data = Void>
typedef Topic<Data>::Subscribers ecl::SigSlot< Data >::Subscribers

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

Definition at line 65 of file sigslot.hpp.

Constructor & Destructor Documentation

◆ SigSlot() [1/3]

template<typename Data = Void>
ecl::SigSlot< Data >::SigSlot ( )
inline

Used only by signals where the function callback automatically defaults to the emit() function.

Definition at line 75 of file sigslot.hpp.

◆ SigSlot() [2/3]

template<typename Data = Void>
ecl::SigSlot< Data >::SigSlot ( void(*)(Data)  f)
inline

Used by slots loading global or static functions.

Parameters
f: the global/static function.

Definition at line 83 of file sigslot.hpp.

◆ SigSlot() [3/3]

template<typename Data = Void>
template<typename C >
ecl::SigSlot< Data >::SigSlot ( void(C::*)(Data)  f,
C &  c 
)
inline

Used by slots loading a member function.

Parameters
f: the member function to load.
c: the instance for the member function's class.
Template Parameters
C: the member function's class type.

Definition at line 94 of file sigslot.hpp.

◆ ~SigSlot()

template<typename Data = Void>
ecl::SigSlot< Data >::~SigSlot ( )
inline

Disconnects the sigslot completely.

This is a rather elaborate process, it must first disconnect from any signals to ensure no new callbacks are instantiated, then check to see that there are no callbacks actually running, block if so, then finalise any deletions.

Definition at line 105 of file sigslot.hpp.

Member Function Documentation

◆ connectSignal()

template<typename Data = Void>
void ecl::SigSlot< Data >::connectSignal ( const std::string &  topic)
inline

Connect a signal to the specified topic.

If the topic doesn't exist, it will be created and the signal connected. If it does exist, it will connect with a set of slots also currently linked to the topic.

Definition at line 152 of file sigslot.hpp.

◆ connectSlot()

template<typename Data = Void>
void ecl::SigSlot< Data >::connectSlot ( const std::string &  topic)
inline

Connect a slot to the specified topic.

If the topic doesn't exist, it will be created and the slot connected. If it does exist, it will pass on its link details to any signals also connected to the topic.

Definition at line 170 of file sigslot.hpp.

◆ disconnect() [1/2]

template<typename Data = Void>
void ecl::SigSlot< Data >::disconnect ( )
inline

Disconnect the sigslot from all topics.

This completely disconnects the sigslot.

Definition at line 191 of file sigslot.hpp.

◆ disconnect() [2/2]

template<typename Data = Void>
void ecl::SigSlot< Data >::disconnect ( const std::string &  topic)
inline

Disconnect the sigslot from the specified topic.

Definition at line 181 of file sigslot.hpp.

◆ emit()

template<typename Data = Void>
void ecl::SigSlot< Data >::emit ( Data  data)
inline

Emit a signal along with the specified data.

This is used by signals when emitting to slots.

Definition at line 120 of file sigslot.hpp.

◆ process()

template<typename Data = Void>
void ecl::SigSlot< Data >::process ( Data  data)
inline

Process the callback function loaded into this sigslot.

This is used by slots with their loaded functions or relaying signals with their emit() methods.

Definition at line 137 of file sigslot.hpp.

◆ subscribedTopics()

template<typename Data = Void>
const std::set<std::string>& ecl::SigSlot< Data >::subscribedTopics ( )
inline

Definition at line 204 of file sigslot.hpp.
