Detailed Description

In contrast to a TBlockVector, a TUniformBlockVector stores only uniform sub vectors and, furthermore, also contains local data. Hence, the data of the whole vector is not stored in the leaf vectors alone, as in the case of a TBlockVector, but is distributed through the complete hierarchy of a TUniformBlockVector.
