class Signal

Detailed Description

represents a connection to a signal

This type is copyable. Any copy can be used to disconnect.

Definition at line 34 of file connection.hpp.

Constructor & Destructor Documentation

◆ Connection()

constexpr ndn::util::signal::Connection::Connection ( )

Member Function Documentation

◆ disconnect()

void ndn::util::signal::Connection::disconnect ( )

disconnects from the signal

If the connection is already disconnected, or if the Signal has been destructed, this operation has no effect.
During signal emission, attempting to disconnect a connection other than the executing handler's own connection results in undefined behavior.

◆ isConnected()

bool ndn::util::signal::Connection::isConnected ( ) const

check if connected to the signal

false if disconnected from the signal

◆ operator==()

bool ndn::util::signal::Connection::operator== ( const Connection other) const

compare for equality

Two connections are equal if they both refer to the same connection that isn't disconnected, or they are both disconnected.

◆ operator!=()

bool ndn::util::signal::Connection::operator!= ( const Connection other) const
