Constructor & Destructor Documentation

◆ CommunicationPattern()

LinearAlgebra::TpetraWrappers::CommunicationPattern::CommunicationPattern ( const IndexSet vector_space_vector_index_set,
const IndexSet read_write_vector_index_set,
const MPI_Comm communicator 
)

Reinitialize the communication pattern. The first argument vector_space_vector_index_set is the index set associated to a VectorSpaceVector object. The second argument read_write_vector_index_set is the index set associated to a ReadWriteVector object.

Definition at line 34 of file trilinos_tpetra_communication_pattern.cc.

◆ reinit()

void LinearAlgebra::TpetraWrappers::CommunicationPattern::reinit ( const IndexSet vector_space_vector_index_set,
const IndexSet read_write_vector_index_set,
const MPI_Comm communicator 
)
overridevirtual

Reinitialize the object.

Implements LinearAlgebra::CommunicationPatternBase.

◆ get_mpi_communicator()

const MPI_Comm & LinearAlgebra::TpetraWrappers::CommunicationPattern::get_mpi_communicator ( ) const
overridevirtual

Return the underlying MPI communicator.
