Detailed Description

template<class T>
class RTT::mqueue::MQTemplateProtocol< T >

For each transportable type T, specify the conversion functions.

Warning

This can only be used if T is a trivial type without meaningful (copy) constructor. For all other cases, or in doubt, use the MQSerializationProtocol class.

Member Typedef Documentation

template<class T >

typedef T RTT::mqueue::MQTemplateProtocol< T >::UserType

The given T parameter is the type for reading DataSources.

Member Function Documentation

template<class T >

RTT::mqueue::MQTemplateProtocol< T >::BOOST_STATIC_ASSERT

(

!boost::has_virtual_destructor< T >::value

)

We don't support types with virtual functions ! TODO: use this type trait to make the necessary adjustments in the memcopy (adding the vptr table offset).

template<class T >

virtual std::pair<void const*,int> RTT::mqueue::MQTemplateProtocol< T >::fillBlob ( base::DataSourceBase::shared_ptr  source, void *  blob, int  size, void *  cookie  ) const

inlinevirtual

Create an transportable object for a protocol which contains the value of source. This must be a real-time function which does not allocate memory

Parameters

source	The data to be read
blob	Suggested target memory area to write to. In case the type marshaller does not need this, it will return an alternative as a first element in the returned std::pair.
size	The size of the memory area pointed by blob

Returns

Returns (0,0) if the filling failed, otherwise, points to the filled memory area and the effectively written size. The returned pointer may differ from blob, in case blob was not used. The returned size must be lower or equal than size

Implements RTT::types::TypeMarshaller.

Definition at line 76 of file MQTemplateProtocol.hpp.

template<class T >

virtual unsigned int RTT::mqueue::MQTemplateProtocol< T >::getSampleSize ( base::DataSourceBase::shared_ptr  sample, void *  cookie  ) const

inlinevirtual

Returns the size in bytes of a marshalled data element.

Returns

the size.

Implements RTT::types::TypeMarshaller.

Definition at line 94 of file MQTemplateProtocol.hpp.

template<class T >

virtual bool RTT::mqueue::MQTemplateProtocol< T >::updateFromBlob ( const void *  blob, int  size, base::DataSourceBase::shared_ptr  target, void *  cookie  ) const

inlinevirtual

Update target with the contents of blob which is an object of a protocol. The given data source is guaranteed to be an AssignableDataSource

Implements RTT::types::TypeMarshaller.
