Detailed Description

template<typename VectorType>
struct IsBlockVector< VectorType >

A class that can be used to determine whether a given type is a block vector type or not. For example,

has the value false, whereas

is true. This is sometimes useful in template contexts where we may want to do things differently depending on whether a template type denotes a regular or a block vector type.

◆ check_for_block_vector() [1/2]

template<typename VectorType >
template<typename T >
static std::true_type IsBlockVector< VectorType >::check_for_block_vector ( const BlockVectorBase< T > *  )

Overload returning true if the class is derived from BlockVectorBase, which is what block vectors do.

◆ check_for_block_vector() [2/2]

template<typename VectorType >
static std::false_type IsBlockVector< VectorType >::check_for_block_vector (   ...)

Catch all for all other potential vector types that are not block matrices.
