Detailed Description

template<>
class ecl::SigSlot< Void >

Not for direct use, provides the power behind both void 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. This is the specialisation of the general case for void callbacks.

Member Typedef Documentation

typedef std::map<std::string, const Subscribers*> ecl::SigSlot< Void >::PublicationMap

Stores publishing topics and their followers.

Definition at line 218 of file sigslot.hpp.

typedef Topic<Void>::Subscribers ecl::SigSlot< Void >::Subscribers

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

Definition at line 217 of file sigslot.hpp.

Constructor & Destructor Documentation

ecl::SigSlot< Void >::SigSlot ( )

inline

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

Definition at line 224 of file sigslot.hpp.

ecl::SigSlot< Void >::SigSlot ( VoidFunction  f )

inline

Used by slots loading global or static functions.

Parameters

f	: the global/static function.

Definition at line 232 of file sigslot.hpp.

template<typename C >

ecl::SigSlot< Void >::SigSlot ( void(C::*)(void)  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 243 of file sigslot.hpp.

ecl::SigSlot< Void >::~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 254 of file sigslot.hpp.

Member Function Documentation

void ecl::SigSlot< Void >::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 301 of file sigslot.hpp.

void ecl::SigSlot< Void >::connectSlot ( const std::string &  topic )

inline

Connect a slot to the specified topic.

Definition at line 315 of file sigslot.hpp.

void ecl::SigSlot< Void >::decrHandles ( )

inline

Decrement the counter for the number of copies of this object.

Definition at line 262 of file sigslot.hpp.

void ecl::SigSlot< Void >::disconnect ( const std::string &  topic )

inline

Disconnect the sigslot from 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 329 of file sigslot.hpp.

void ecl::SigSlot< Void >::disconnect ( )

inline

Disconnect the sigslot from all topics.

This completely disconnects the sigslot.

Definition at line 339 of file sigslot.hpp.

void ecl::SigSlot< Void >::emit ( )

inline

Emit a signal.

This is used by signals when emitting to slots.

Definition at line 269 of file sigslot.hpp.

const unsigned int& ecl::SigSlot< Void >::handles ( ) const

inline

Number of copies of this object.

Definition at line 260 of file sigslot.hpp.

void ecl::SigSlot< Void >::incrHandles ( )

inline

Increment the counter for the number of copies of this object.

Definition at line 261 of file sigslot.hpp.

void ecl::SigSlot< Void >::process ( Void  void_arg = Void() )

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 286 of file sigslot.hpp.
