Detailed Description

template<typename MatrixType>
struct internal::AffineConstraints::IsBlockSparsityPattern< MatrixType >

A class that can be used to determine whether a given type is a block sparsity pattern type or not. In this, it matches the IsBlockMatrix class.

template<typename MatrixType >

template<typename T >

static std::true_type internal::AffineConstraints::IsBlockSparsityPattern< MatrixType >::check ( const BlockSparsityPatternBase< T > *  )

staticprivate

Overload returning true if the class is derived from BlockSparsityPatternBase, which is what block sparsity patterns do.

check() [2/2]

template<typename MatrixType >

static std::false_type internal::AffineConstraints::IsBlockSparsityPattern< MatrixType >::check (   ... )

staticprivate

Catch all for all other potential types that are then apparently not block sparsity patterns.

template<typename MatrixType >

const bool internal::AffineConstraints::IsBlockSparsityPattern< MatrixType >::value

static

Initial value:

=
        std::is_same<decltype(check(std::declval<MatrixType *>())),
                     std::true_type>::value

A statically computable value that indicates whether the template argument to this class is a block sparsity pattern (in fact whether the type is derived from BlockSparsityPatternBase<T>).
