BDE Libraries, An Orientation
summary
BDE (github.com/bloomberg/bde) presents a concrete library ecosystem: 900 documented components organized into 47 packages and 5 package groups, each with a test driver that proves contracts. Core features include allocator-enabled containers, fine-grained componentization, a class taxonomy (value semantics, mechanisms, utilities, protocols), doxygen-based documentation with usage examples, and a layered assertion system (safe / assert safe / opt) whose handlers can abort, sleep for debugger attach, or throw so failures can be logged or escalated.
