Detailed Description

template<typename v_src, typename v_dst, int... prp>
struct object_s_di< v_src, v_dst, OBJ_ENCAP, prp... >

It copy the properties from one object to another.

Given a set of properties for the destination object (0,1,3) it copy that properties to the source object properties (0,1,2)

For object we mean an object that follow the OpenFPM data structure format, see openFPM_data wiki for more information

Create a compile-time object and copy to the selected properties

typedef Point_test<float> p;
typedef Point_test<float>::type vboost;
typedef object_creator<Point_test<float>::type,0,1,4>::type vboost_red;
// fill the source properties 0,1,2 with data
boost::fusion::at_c<0>(src.data) = 1.0;
boost::fusion::at_c<1>(src.data) = 2.0;
for (size_t i = 0 ; i < 3 ; i++)
boost::fusion::at_c<2>(src.data)[i] = i + 5.0;
// copy from src to dst
object_s_di<object<vboost_red>,object<vboost>,OBJ_NORMAL,0,1,4>(src,dst);
// Check the result
BOOST_REQUIRE_EQUAL(boost::fusion::at_c<p::x>(dst.data),1.0);
BOOST_REQUIRE_EQUAL(boost::fusion::at_c<p::y>(dst.data),2.0);
for (size_t i = 0 ; i < 3 ; i++)
BOOST_REQUIRE_EQUAL(boost::fusion::at_c<p::v>(dst.data)[i],i + 5.0);

Create a compile-time Encap object and copy to the selected properties

v_point.resize(2);
v_point_red.resize(2);
v_point_red.template get<0>(0) = 11.0;
v_point_red.template get<1>(0) = 12.0;
for (size_t i = 0 ; i < 3 ; i++)
v_point_red.template get<2>(0)[i] = i + 15.0;
auto dst_e = v_point.get(0);
auto src_e = v_point_red.get(0);
BOOST_REQUIRE_EQUAL(v_point.get(0).template get<p::x>(),11.0);
BOOST_REQUIRE_EQUAL(v_point.get(0).template get<p::y>(),12.0);
for (size_t i = 0 ; i < 3 ; i++)
BOOST_REQUIRE_EQUAL(v_point.get(0).template get<p::v>()[i],i + 15.0);
