defaultnoexcept

ScopedConnection() [2/4]

ndn::util::signal::ScopedConnection::ScopedConnection ( const ScopedConnection &  )

delete

ScopedConnection() [3/4]

ndn::util::signal::ScopedConnection::ScopedConnection ( ScopedConnection &&  )

inlinedefaultnoexcept

Move constructor.

ScopedConnection() [4/4]

ndn::util::signal::ScopedConnection::ScopedConnection ( Connection  connection )

noexcept

Implicit constructor from Connection.

Parameters

connection

the Connection to be disconnected upon destruction

Definition at line 28 of file scoped-connection.cpp.

~ScopedConnection()

ndn::util::signal::ScopedConnection::~ScopedConnection

(

)

Destructor, automatically disconnects the connection.

Definition at line 43 of file scoped-connection.cpp.

Member Function Documentation

disconnect()

void ndn::util::signal::ScopedConnection::disconnect

(

)

Manually disconnect the connection.

Definition at line 49 of file scoped-connection.cpp.

isConnected()

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

noexcept

Check if the connection is connected to the signal.

Returns

false when a default-constructed connection is used, the connection is released, or the connection is disconnected

Definition at line 55 of file scoped-connection.cpp.

operator=() [1/3]

ScopedConnection& ndn::util::signal::ScopedConnection::operator= ( const ScopedConnection &  )

delete

operator=() [2/3]

ScopedConnection & ndn::util::signal::ScopedConnection::operator= ( ScopedConnection &&  )

inlinedefaultnoexcept

Move assignment operator.

operator=() [3/3]

ScopedConnection & ndn::util::signal::ScopedConnection::operator=

(

Connection

connection

)

Assign a connection.

If a different connection has been assigned to this instance previously, that connection will be disconnected immediately.

Definition at line 34 of file scoped-connection.cpp.

release()

void ndn::util::signal::ScopedConnection::release ( )

noexcept

Release the connection so that it won't be disconnected when this ScopedConnection is destructed.

Definition at line 61 of file scoped-connection.cpp.
