Member Function Documentation

◆ disconnect()

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

Disconnects from the signal.

Note: If the connection is already disconnected, or if the Signal has been destructed, this operation has no effect.

Warning: During signal emission, attempting to disconnect a connection other than the executing handler's own connection results in undefined behavior.

Definition at line 32 of file connection.cpp.

◆ isConnected()

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

inlinenoexcept

Check if connected to the signal.

Definition at line 57 of file connection.hpp.

◆ operator==

bool operator==	(	const Connection &	lhs,
		const Connection &	rhs
	)

friend

Compare for equality.

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