protected

void CYISignalBase::Disconnect ( CYISignalHandler & rSignalHandler )

Disconnects every connection between a CYISignal and the given CYISignalHandler. All daisy-chained signals will also be disconnected.

Note: This is done automatically when the CYISignal goes out of scope or is deleted.; If the connection doesn't exists with a given slot, it won't have any effect.; This function is thread-safe.

See also: CYISignalHandler::Disconnect(CYISignalBase &rSignal)

void CYISignalBase::Disconnect ( CYISignalConnectionID connectionID )

Disconnects a single connection identified by connectionID. If no such connection exists, this function has no effect.

Note: This function is thread-safe.

void CYISignalBase::Disconnect ( CYISignalBase & rSignal )

Disconnects every daisy-chained connections between this signal and the given signal.

Note: This is done automatically when the CYISignal goes out of scope or is deleted.; This function is thread-safe.

See also: CYISignalHandler::Disconnect(CYISignalBase &rSignalHandler)

void CYISignalBase::ExclusiveLock ( CYIRecursiveSpinLock & signalMutex ) const

protected

Obtains exclusive lock with this CYISignalBase and every CYISignalHandler found in the connection list. This function will keep trying to acquire the locks until every objects are locked. The purpose of this function is to avoid deadlocks.

Note: This function must be followed by ExclusiveUnlock();; This function is thread-safe.

void CYISignalBase::ExclusiveLock	(	const CYISignalHandler &	rSignalHandler,
		CYIRecursiveSpinLock &	signalMutex
	)		const

protected

Obtains exclusive lock with this CYISignalBase and every CYISignalHandler found in the connection list. This function will keep trying to acquire the locks until every objects are locked. The purpose of this function is to avoid deadlocks.

Note: This function must be followed by ExclusiveUnlock(rSignalHandler);; This function is thread-safe.

void CYISignalBase::ExclusiveUnlock ( CYIRecursiveSpinLock & signalMutex ) const

protected

Unlocks every CYISignalHandler found in the connection and unlocks this CYISignalBase.

Note: This function is thread-safe.

void CYISignalBase::ExclusiveUnlock	(	const CYISignalHandler &	rSignalHandler,
		CYIRecursiveSpinLock &	rSignalMutex
	)		const

protected

Unlocks a specific CYISignalHandler found in the connection list and unlocks this CYISignalBase.

Note: This function is thread-safe.

bool CYISignalBase::HasConnection ( const CYISignalHandler & rSignalHandler ) const

protected

Checks if this instance has a connection to a given CYISignalHandler.

Warning: This function is not thread-safe.

virtual bool CYISignalBase::IsConnected ( ) const

overridevirtual

Checks if at least one connection has been established with any CYISignalHandler (or to any static functions).

Note: This function is thread-safe.

See also: IsConnected(const CYISignalBase &rSignal) const; IsConnected(const CYISignalHandler &rSignalHandler) const

Reimplemented from CYISignalHandler.

virtual bool CYISignalBase::IsConnected ( const CYISignalBase & rSignal ) const

overridevirtual

Checks if a CYISignal is connected to another via a daisy chain connection.

Example:

CYISignal<int32_t, int32_t, int32_t, int32_t> MySignal1;
CYISignal<int32_t, int32_t, int32_t, int32_t> MySignal2;
bool ConnectMySignalToMyHandlerAndCheck()
{
    MySignal1.Connect(MySignal2); // daisy-chain
    return MySignal1.IsConnected(MySignal2) && MySignal2.IsConnected(MySignal1);
}

Note: This function is thread-safe.

See also: IsConnected() const; IsConnected(const CYISignalHandler &rSignalHandler) const

Reimplemented from CYISignalHandler.

bool CYISignalBase::IsConnected ( const CYISignalHandler & rSignalHandler ) const

Checks if at least one connection has been established with a given CYISignalHandler.

Note: This function is thread-safe.

See also: IsConnected() const; IsConnected(const CYISignalBase &rSignal) const

bool CYISignalBase::IsConnected ( CYISignalConnectionID connectionID ) const

Checks if a connection has been established and is identified by connectionID.

Note: This function is thread-safe.

CYISignalBase& CYISignalBase::operator= ( const CYISignalBase & rSignal )

protected

void CYISignalBase::RegisterToSignalHandler ( const CYISignalHandler & rSignalHandler )

protected

Adds this CYISignalBase instance into the signal list of a CYISignalHandler.

Warning: This function is not thread-safe.

void CYISignalBase::RemoveAllConnections ( NotifyFlag notifyHandler )

protected

Disconnects every connection from every CYISignalHandler and from every static functions. All daisy-chained signals will also be disconnected.

Warning: This function is not thread-safe.

void CYISignalBase::RemoveConnection	(	CYISignalHandler &	rSignalHandler,
		NotifyFlag	notifyHandler
	)

protected

Disconnects every connection between a CYISignal and the given CYISignalHandler without severing the connection from the CYISignalHandler to this instance.

This function is meant to be used by the CYISignalHandler only, when the connection termination occurs on the CYISignalHandler first.

Warning: This function is not thread-safe.

void CYISignalBase::UnregisterFromSignalHandler ( CYISignalHandler & rSignalHandler )

protected

Removes this CYISignalBase instance from the signal list of an CYISignalHandler.

Warning: This function is not thread-safe.
