Description

This package defines, 'bdlbb::Blob', a vocabulary type for other 'bdl' packages. A 'bdlbb::Blob' object consists of a sequence of 'bdlbb::BlobBuffer' objects, each of which have a shared pointer to underlying memory. A protocol is defined for factories to manage 'bdlbb::BlobBuffer' objects, and a concrete implementation is provided. Other components define non-primitive operations on 'bdlbb::Blob's.

Hierarchical Synopsis

The 'bdlbb' package currently has 5 components having 2 levels of physical dependency. The list below shows the hierarchical ordering of the components. The order of components within each level is not architecturally significant, just alphabetical.
