Detailed Description
template<class TMatrix>
class ug::ComPol_MatAddRowsOverlap0< TMatrix >
Communication Policy to copy slave couplings to master row.
This Communication policy assumes that the matrix is stored additively with no overlap. It then copies the row entries of the slaves indices to the corresponding master rows. Only those values are copied that have if the index the slave couples to has also a representation on the other process. This means that couplings to inner indices or to other slave/master, that have only connections to other processes, are not taken into account.

Constructor & Destructor Documentation
◆ ComPol_MatAddRowsOverlap0()
|
inline |
Constructor setting the vector.
vGlobalID must have size >= mat.num_rows()
References ug::ComPol_MatAddRowsOverlap0< TMatrix >::m_rMat, and UG_ASSERT.
Member Function Documentation
◆ begin_layout_extraction()
|
inlinevirtual |
signals the beginning of a layout extraction.
the default implementation returns true and does nothing else. This method is only called on processes which extract data.
Reimplemented from pcl::ICommunicationPolicy< IndexLayout >.

◆ collect()

inlinevirtual |
writes the interface values into a buffer that will be sent
