Detailed Description

template<typename T>
struct adtf::base::adtf_memory_forward< T >

bring latest ant::adtf_memory_forward to users scope

Concept template class for non trivial penguin::adtf_memory types of type T to specialize the usage of adtf_memory<T>.

Template Parameters

T	Type to specialize adtf_memory_forward for.

Remarks

If no specialization exists for your type T the usage of penguin::adtf_memory and adtf_memory_intf will fail!

Following methods needs to be implemented:

static tResult Assign(T* pAssignValue,
                    const size_t szStaticSize,
                    const void* pValueToSet,
                    const size_t  szSizeToSet);
static const void* GetPtr(const T* pAssignValue);
static size_t GetSize(const T* pAssignValue, const size_t szStaticSize);

Example for the adtf_util::cMemoryBlock :

  template <>
struct adtf_memory_forward<adtf_util::cMemoryBlock>
{
public:
    static tResult Assign(adtf_util::cMemoryBlock* pAssignValue,
                            const size_t szStaticSize,
                            const void* pValueToSet,
                            const size_t  szSizeToSet)
    {
        return pAssignValue->Set(pValueToSet, szSizeToSet);
    }
    static const void* GetPtr(const adtf_util::cMemoryBlock* pAssignValue)
    {
        return pAssignValue->GetPtr();
    }
    static size_t GetSize(const adtf_util::cMemoryBlock* pAssignValue, const size_t szStaticSize)
    {
        return static_cast<tSize>(pAssignValue->GetSize());
    }
};

Member Function Documentation

Assign()

template<typename T>

static tResult adtf::base::ant::adtf_memory_forward< T >::Assign ( T * pAssignValue, const size_t szStaticSize, const void * pValueToSet, const size_t szSizeToSet )

inlinestatic

Sets (copy) the memory value pValueToSet of size in bytes szSizeToSet to the of container class T in parameter pAssignValue. Usually this implementation creates a deep copy.

Parameters

[in]	pAssignValue	pointer to the container class T. Must be a valid constructed object.
[in]	szStaticSize	implementation details: max size of static pre allocated memory within AssignValue. if set no dynamic allocation possible.
[in]	pValueToSet	raw pointer to the memory to set
[in]	szSizeToSet	size in bytes of pValueToSet

Returns

Standard Result Code

GetPtr()

template<typename T>

static const void * adtf::base::ant::adtf_memory_forward< T >::GetPtr ( const T * pAssignValue )

inlinestatic

Gets the memory pointer to the of container class T in parameter pAssignValue.

Parameters

[in]

pAssignValue

pointer to the container class T. Must be a valid constructed object.

Returns

valid raw memory pointer to the mamory with pAssignValue.

Remarks

Make sure the pointer is still valid after function returned.

GetSize()

template<typename T>

static size_t adtf::base::ant::adtf_memory_forward< T >::GetSize ( const T * pAssignValue, const size_t szStaticSize )

inlinestatic

Gets size in bytes of the memory pointer of container class T in parameter pAssignValue.

Parameters

[in]	pAssignValue	pointer to the container class T. Must be a valid constructed object.
[in]	szStaticSize	size of the pointers buffer if container class is a static sized type

Returns

the size in bytes.
