sparse_dense_view< SparseVectorCollection >

Description

sparse_dense_view is a DenseVectorCollection and a View that is used to access the non-zero elements of a SparseVectorCollection without changing the non-zero pattern. The size() of the sparse_dense_view is equal to the nnz() of its source.

Example

Definition

Defined in glas/view/sparse_dense_view.hpp.

Template parameters

Parameter	Description	Default
`SparseVectorCollection`	the type of the source-vector

Model of

DenseVectorCollection and View.

Type requirements

SparseVectorCollection Must be a model of SparseVectorCollection

Members

Member	Where defined	Comment
`size_type`	VectorExpression	Defined as SparseVectorCollection::`nnz_type`
`value_type`	VectorExpression	Defined as SparseCollection`::value_type`
`const_reference`	VectorExpression
`reference`	Collection	Equal to `const_reference` unless the SparseVectorCollection is really a Collection (and not just an Expression) in which case it is defined as `SparseVectorCollection::reference`.
`source_type`	View
`sparse_dense_view(SparseCollection const&)`	View
`sparse_dense_view(sparse_dense_view const&)`	Assignable	Copy constructor
`void operator=(sparse_dense_view const&)`	Assignable	Copies the contents of the view. Thus this will not make the view point to another source
`bool operator==(sparse_dense_view const&) const`	EqualityComparable	Compares the content of the underlying collection
`bool operator!=(sparse_dense_view const&) const`	EqualityComparable
`size_type size() const`	VectorExpression	Equal to `source().nnz()`
`const_reference operator[]( size_type ) const`	DenseExpression	Returns `source().nz(i)`
`reference operator[]( size_type )`	DenseCollection	Returns `source().nz(i)`
`source_type& source()`	UnaryExpression
