Detailed Description
template<typename VECTOR, typename OPERATOR>
class geos::BlockOperator< VECTOR, OPERATOR >
Concrete 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 storage for sub-block operators. The OPERATOR type needs to be default-constructible.
