Detailed Description

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

This class is responsible for creating and initializing the data memory space on the heap:

  • compute the required memory size and allocate the memory
  • map each field into the data store

Constructor & Destructor Documentation

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

generates the heap factory

Parameters
classNamename of the device-class
classVersionversion of the device-class

Member Function Documentation

template<typename GlobalDeviceType , typename DomainStoreType , typename DevInstType >
bool fesa::HeapFactory< GlobalDeviceType, DomainStoreType, DevInstType >::setUpMemory ( )
virtual

creates the memory on the heap, maps and initializes all the fields

Returns
true: heap-memory has been created

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