Detailed Description

This class implements a wrapper to Trilinos Import.

Definition at line 41 of file trilinos_epetra_communication_pattern.h.

Constructor & Destructor Documentation

◆ CommunicationPattern()

LinearAlgebra::EpetraWrappers::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 36 of file trilinos_epetra_communication_pattern.cc.

◆ reinit()

void LinearAlgebra::EpetraWrappers::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::EpetraWrappers::CommunicationPattern::get_mpi_communicator ( ) const
overridevirtual

Return the underlying MPI communicator.

Implements LinearAlgebra::CommunicationPatternBase.

◆ get_epetra_import()

const Epetra_Import & LinearAlgebra::EpetraWrappers::CommunicationPattern::get_epetra_import ( ) const

Return the underlying Epetra_Import object.
