Detailed Description

template<typename MetaTypeStruct>
class adtf::streaming::ant::stream_meta_type< MetaTypeStruct >

Generator template stream_meta_type to create a StreamMetaType Class for the Type T.

Template Parameters

MetaTypeStruct

The type MetaTypeStruct needs to be a class with following concept:

Minimal constraint:

struct stream_meta_type_plain
{
    static constexpr const char* const MetaTypeName = <your meta type name as string>;
    static void SetProperties(const adtf::ucom::iobject_ptr<adtf::base::IProperties>& pProperties)
    {
       //your properties to set
       pProperties->SetProperty(adtf::base::property<adtf_util::cString>(PlainTypeProperty, ""));
    }
};

Is compatible:

Additionally it is possible to implement a IsCompabible method:

struct stream_meta_type_plain
{
    static constexpr const char* const MetaTypeName = <your meta type name as string>;
    static void SetProperties(const adtf::ucom::iobject_ptr<adtf::base::IProperties>& pProperties)
    {
       //your properties to set
       pProperties->SetProperty(adtf::base::property<adtf_util::cString>(PlainTypeProperty, ""));
    }
    static void IsCompatible(const IStreamType& oSourceType,
                              const IStreamType& oDestinationType)
    {
        // implement your comapible crititeria here!!
    }
};

Member Function Documentation

IsCompatible()

tResult IsCompatible ( const IStreamType &  oCheckedType, const IStreamType &  oExpectedType  ) const

inlineoverride

The IsCompatible implementation of this generator class will decide at compile time wether to use the MetaTypeStruct::IsCompatible method if provided or to use the cStreamMetaType::IsCompatible default implementation.

Parameters

oCheckedType	The type to check
oExpectedType	The base expected type the checked type must be compatible to for a successfully call.
