protected

◆ Disconnect() [1/3]

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.

CYISignalHandler::Disconnect(CYISignalBase &rSignal)

◆ Disconnect() [2/3]

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.

◆ Disconnect() [3/3]

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)

◆ ExclusiveLock() [1/2]

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.

◆ ExclusiveLock() [2/2]

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.

◆ ExclusiveUnlock() [1/2]

void CYISignalBase::ExclusiveUnlock ( CYIRecursiveSpinLock &  signalMutex) const
protected

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

Note
This function is thread-safe.

◆ ExclusiveUnlock() [2/2]

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.

◆ HasConnection()

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.

◆ IsConnected() [1/4]

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.

◆ IsConnected() [2/4]

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.

◆ IsConnected() [3/4]

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

◆ IsConnected() [4/4]

bool CYISignalBase::IsConnected ( CYISignalConnectionID  connectionID) const

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

Note
This function is thread-safe.

◆ operator=()

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

◆ RegisterToSignalHandler()

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.

◆ RemoveAllConnections()

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.

◆ RemoveConnection()

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

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.

◆ UnregisterFromSignalHandler()

void CYISignalBase::UnregisterFromSignalHandler ( CYISignalHandler &  rSignalHandler)
protected

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