Helper class that wraps a streaming::ant::IBindingClient.

See cGraphObject::CreateInterfaceClient.

Example Usage

#include <adtffiltersdk/adtf_filtersdk.h>
 
class IMyInterface: public adtf::ucom::IObject
{
    public:
        ADTF_IID(IMyInterface, "my_interface.iid");
 
    public:
        virtual void DoSomething() = 0;
};
 
class cMyFilter: public adtf::filter::cFilter
{
    public:
        ADTF_CLASS_ID_NAME(cMyFilter, "my_filter.filter.example.cid", "My Filter");
 
        cMyFilter()
        {
            m_oInterfaceClient = CreateInterfaceClient<IMyInterface>("my_interface");
            CreateRunner("do_something");
        }
 
        tResult Process(adtf::base::tNanoSeconds /*tmTrigger*/,
                        adtf::streaming::IRunner* /*pRunner*/) override
        {

            RETURN_NOERROR;
        }
