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,

IsBlockVector<Vector<double> >::value

has the value false, whereas

IsBlockVector<BlockVector<double> >::value

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.
