Detailed Description

template<typename VECTOR>
class geos::BlockVectorWrapper< VECTOR >

"Shallow" representation of a block vector.

Template Parameters

VECTOR type of sub-vectors

This extends BlockVectorView 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 vector representation from pre-existing blocks.
