Member Function Documentation

void ndn::util::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.

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

noexcept

check if connected to the signal

Returns

false if disconnected from the signal
