Detailed Description

Create a null selector.

This is a null op selector (will return input vector)

Member Function Documentation

communicator()

virtual AMP_MPI AMP::LinearAlgebra::VectorSelector::communicator ( const Vector &  vec ) const

virtualinherited

Returns the communicator for the subset.

Parameters

[in]

vec

The Vector to match

This function will return the proper communicator given the current vector. For most subsetters, this will be the same communicator as the current vector, however some subsetters (MeshSelector) may opperate on a different (smaller) comm.

Reimplemented in AMP::LinearAlgebra::VS_Comm, and AMP::LinearAlgebra::VS_Mesh.

create()

static std::shared_ptr< VectorSelector > AMP::LinearAlgebra::VectorSelector::create ( const std::vector< std::shared_ptr< VectorSelector > > &  selectors )

staticinherited

Create a VectorSelector.

Create a VectorSelector that applies a set of selectors which all must be met for the subset operation

Parameters

[in]

selectors

A list of subsequent selectors to apply

isSelected()

bool AMP::LinearAlgebra::NullSelector::isSelected ( const Vector &  vec ) const

inlineoverridevirtual

Returns true if Vector grossly matches a selection condition.

Parameters

[in]

vec

The Vector to match

Base class defaults to accepting all vectors.

Implements AMP::LinearAlgebra::VectorSelector.

Definition at line 228 of file VectorSelector.h.

subset()

std::shared_ptr< Vector > AMP::LinearAlgebra::NullSelector::subset ( std::shared_ptr< Vector >  vec ) const

inlineoverridevirtual

Subset the given vector.

Parameters

[in]

vec

The Vector to subset

Base class defaults to returning all data in the vector

Implements AMP::LinearAlgebra::VectorSelector.
