Here is the call graph for this function:

CSize Memory::occupiedMemorySizeByActors ( ) const

occupiedMemorySizeByActors () The function returns the amount of memory used by the bound actors.

References CompBindings::getCurVal(), and memActor.

Referenced by reserveMemory(), and LoadBalanceBinding::sortTilesOnLoad().

Here is the call graph for this function:

bool Memory::releaseMemory ( SDFchannel * c )

releaseMemory () The function releases the memory reserved by SDF channl c and removes its binding to the memory.

References memChannel, and CompBindings::unbind().

Here is the call graph for this function:

bool Memory::releaseMemory ( SDFactor * a )

releaseMemory () The function releases the memory reserved by SDF actor a and removes its binding to the memory.

References memActor, and CompBindings::unbind().

Referenced by LoadBalanceBinding::releaseConnectionResources(), LoadBalanceBinding::releaseResources(), and LoadBalanceBinding::updateStorageSpaceAllocation().

Here is the call graph for this function:

bool Memory::releaseMemory ( )

releaseMemory () The function releases the memory.

References memChannel, and CompBindings::unbind().

Here is the call graph for this function:

bool Memory::reserveMemory	(	SDFchannel *	c,
		CSize	sz
	)

reserveMemory () The function tries to reserve memory space with size sz for the SDF channl c. On success, it returns true and it creates a binding between the channel and the memory. Else, it returns false and no binding is created.

References availableMemorySize(), CompBindings::bind(), memChannel, and ComponentBinding::setValue().

Here is the call graph for this function:

bool Memory::reserveMemory ( CSize sz )

reserveMemory () The function tries to reserve memory space with size sz. On success, it returns true. Else, it returns false and no binding is created.

Here is the call graph for this function:

bool Memory::reserveMemory	(	SDFactor *	a,
		CSize	sz
	)

reserveMemory () The function tries to reserve memory space with size sz for the SDF actor a. On success, it returns true and it creates a binding between the actor and the memory. Else, it returns false and no binding is created.
