Detailed Description

template<typename GlobalDeviceType, typename DomainStoreType, typename DevInstType>
class fesa::MemoryMappedFileFactory< GlobalDeviceType, DomainStoreType, DevInstType >

Class responsible for creating and initializing or attaching to the shared memory as a memory mapped file so it can be shared between separate RT and Server processes.

Constructor & Destructor Documentation

template<typename GlobalDeviceType , typename DomainStoreType , typename DevInstType >

fesa::MemoryMappedFileFactory< GlobalDeviceType, DomainStoreType, DevInstType >::MemoryMappedFileFactory	(	const std::string &	className,
		const std::string &	classVersion
	)

generates the shared-memory name (base on device-class name)

Parameters

className	the name of the class
classVersion	the version of the device-class

Member Function Documentation

template<typename GlobalDeviceType , typename DomainStoreType , typename DevInstType >

bool fesa::MemoryMappedFileFactory< GlobalDeviceType, DomainStoreType, DevInstType >::setUpMemory ( )

virtual

creates the Shared-memory, maps and initializes all the fields

Returns

true: shared-memory has been created

false: shared-memory already exist, has been attached only

Implements fesa::DeviceFactoryImp< GlobalDeviceType, DomainStoreType, DevInstType >.
