Detailed Description

Helper class type that simplifies the usage of the MatrixSymOpGetGMSSymMutable interface for clients.

This takes care of worrying about if the MatrixSymOpGetGMSSymMutable interface is supported or not and remembering to free the DenseLinAlgPack::DMatrixSliceSym view properly.

This class is only to be used on the stack as an automatic variable. For example, to extract a DenseLinAlgPack::DMatrixSliceSym view of an abstract vector and use it to set the matrix to a scalar one could write a function like:

void assign( const value_type alpha, MatrixSymOpGetGMSSymMutable* mat_inout ) {
    MatrixDenseSymMutableEncap  gms_inout(*mat_inout);
  gms_inout() = alpha;
}

In the above code, if the underlying MatrixSymOpGetGMSSymMutable object does not have to perform any dynamic memory allocations and copy in the method MatrixSymOpGetGMSSymMutable::get_sym_gms_view() then the above code will only have a constant time overhead.

Constructor & Destructor Documentation

AbstractLinAlgPack::MatrixDenseSymMutableEncap::MatrixDenseSymMutableEncap ( MatrixSymOpGetGMSSymMutable *  mat_get )

inline

Construct a DenseLinAlgPack::DMatrixSliceSym view from a MatrixSymOpGetGMSSymMutable object.

Definition at line 158 of file AbstractLinAlgPack_MatrixSymOpGetGMSSymMutable.hpp.

AbstractLinAlgPack::MatrixDenseSymMutableEncap::MatrixDenseSymMutableEncap ( MatrixSymOp *  mat )

inline

Construct a DenseLinAlgPack::DMatrixSliceSym view from a MatrixSymOp object.

If dynamic_cast<MatrixSymOpGetGMSSymMutable*>(mat) == NULL then a ??? exception is thrown.

AbstractLinAlgPack::MatrixDenseSymMutableEncap::~MatrixDenseSymMutableEncap ( )

inline

Frees the DenseLinAlgPack::DMatrixSliceSym view and commits the changes.
