Public Member Functions
virtual ErrCode INTERFACE_FUNC	clearDomainSignalWithoutNotification ()=0
	Sets the domain signal to null without notifying the domain signal.
virtual ErrCode INTERFACE_FUNC	enableKeepLastValue (Bool enabled)=0
	Enable or disable keeping last data packet which is using by Signal method getLastValue More...
virtual ErrCode INTERFACE_FUNC	getSignalSerializeId (IString **serializeId)=0
	Gets the signal serilized id. In local device the serilized id matached the signal global id. For remote id it is the signal id in the remote device. More...
virtual ErrCode INTERFACE_FUNC	getKeepLastValue (Bool *keepLastValue)=0
	Returns True if last value calculation is enabled on the signal. More...
virtual ErrCode INTERFACE_FUNC	sendPacketRecursiveLock (IPacket *packet)=0
	Sends a packet through all connections of the signal, acquiring a recursive lock instead of an acquisition lock. More...
Public Member Functions inherited from IBaseObject
virtual ErrCode INTERFACE_FUNC	borrowInterface (const IntfID &intfID, void **obj) const =0
	Returns another interface which is supported by the object without incrementing the reference count. More...
virtual ErrCode INTERFACE_FUNC	dispose ()=0
	Disposes all references held by the object. More...
virtual ErrCode INTERFACE_FUNC	getHashCode (SizeT *hashCode)=0
	Returns hash code of the object. More...
virtual ErrCode INTERFACE_FUNC	equals (IBaseObject *other, Bool *equal) const =0
	Compares object to another object for equality. More...
virtual ErrCode INTERFACE_FUNC	toString (CharPtr *str)=0
	Returns a string representation of the object. More...
Public Member Functions inherited from IUnknown
virtual ErrCode INTERFACE_FUNC	queryInterface (const IntfID &intfID, void **obj)=0
	Returns another interface which is supported by the object and increments the reference count. More...
virtual int INTERFACE_FUNC	addRef ()=0
	Increments the reference count for an interface on an object. More...
virtual int INTERFACE_FUNC	releaseRef ()=0
	Decrements the reference count for an interface on an object. More...

Member Function Documentation

enableKeepLastValue()

virtual ErrCode INTERFACE_FUNC enableKeepLastValue ( Bool  enabled )

pure virtual

Enable or disable keeping last data packet which is using by Signal method getLastValue

Parameters

enabled

Option for enabling method getLastValue

getKeepLastValue()

virtual ErrCode INTERFACE_FUNC getKeepLastValue ( Bool *  keepLastValue )

pure virtual

Returns True if last value calculation is enabled on the signal.

Parameters

[out]

keepLastValue

True if enabled.

getSignalSerializeId()

virtual ErrCode INTERFACE_FUNC getSignalSerializeId ( IString **  serializeId )

pure virtual

Gets the signal serilized id. In local device the serilized id matached the signal global id. For remote id it is the signal id in the remote device.

Parameters

[out]

serializeId

The signal serilized id.

sendPacketRecursiveLock()

virtual ErrCode INTERFACE_FUNC sendPacketRecursiveLock ( IPacket *  packet )

pure virtual

Sends a packet through all connections of the signal, acquiring a recursive lock instead of an acquisition lock.

Parameters

packet

The packet to be sent.
