Detailed Description

template<typename VECTOR, typename OPERATOR = LinearOperator< VECTOR >>
class geos::BlockOperatorWrapper< VECTOR, OPERATOR >

"Shallow" representation of a block operator.

Template Parameters

VECTOR	type of vector that sub-blocks of this view can operate on
OPERATOR	type of operator that can operate on `VECTOR` (can be base class or a more specialized derived class)

This extends BlockOperatorView class by providing a way to assign sub-block pointers. The sub-blocks themselves must be stored elsewhere. Therefore, it's an easy way to assemble a block operator representation from pre-existing blocks.
