Detailed Description

Specialised signal that emits without passing data.

Specialised signal that only emits a signal but passes no data to their respective slots. This is the default template construction for a signal, so you need only use Signal<> to represent the type.

Usage examples are provided in the main page's documentation for this package.

Constructor & Destructor Documentation

◆ Signal() [1/3]

ecl::Signal< Void >::Signal ( )
inline

Default constructor.

This creates a signal but with no default connection. Use connect() to establish a connection.

Definition at line 165 of file signal.hpp.

◆ Signal() [2/3]

ecl::Signal< Void >::Signal ( const std::string &  topic)
inline

Creates a signal and connects.

Definition at line 171 of file signal.hpp.

◆ Signal() [3/3]

ecl::Signal< Void >::Signal ( const Signal< Void > &  signal)
inline

Copy constructor.

This is specially designed so that copying a signal is perfectly acceptable. Copies do not increase the number of emits that are fired - they just preserve the signal when used with things like stl containers. When the last copy disappears, the object destroys its connection automagically.

Parameters
signal: the object to be copied.

Definition at line 186 of file signal.hpp.

◆ ~Signal()

ecl::Signal< Void >::~Signal ( )
inline

Default destructor.

This handles the cleanup operation, first decrementing and then checking if its the last of its instance. If it is, it cleans up the sigslot connection with the sigslots manager.

Definition at line 197 of file signal.hpp.

Member Function Documentation

◆ connect()

void ecl::Signal< Void >::connect ( const std::string &  topic)
inline

Make a connection to the specified topic.

This contacts the sigslots manager to connect the signal to the specified topic - creating the topic if it is not yet existing.

Parameters
topic: the topic to connect to.

Definition at line 211 of file signal.hpp.

◆ connectAsSlot()

void ecl::Signal< Void >::connectAsSlot ( const std::string &  topic)
inline

Connect as a slot, with the emit function loaded.

This allows the signal to act as a relaying signal (effectively a slot with the emit() function loaded.

Parameters
topic: the topic to connect to.

Definition at line 220 of file signal.hpp.

◆ disconnect()

void ecl::Signal< Void >::disconnect ( )
inline

Disconnect the signal from all topics.

This completely disconnects the signal.

Definition at line 226 of file signal.hpp.

◆ emit()

void ecl::Signal< Void >::emit ( )
inline

The primary purpose of the signal, to emit!

Emits a signal with no data.

Definition at line 233 of file signal.hpp.
