bdlbb.h @PURPOSE: Provide flexible, efficient management of message buffers. @MNEMONIC: Basic Development Library Blobs (bdlbb) @SEE_ALSO: bslma @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. .. 2. bdlbb_blobstreambuf bdlbb_blobutil bdlbb_pooledblobbufferfactory bdlbb_simpleblobbufferfactory 1. bdlbb_blob .. /Component Synopsis /------------------ : 'bdlbb_blob': : Provide an indexed set of buffers from multiple sources. : : 'bdlbb_blobstreambuf': : Provide blob implementing the 'streambuf' interface. : : 'bdlbb_blobutil': : Provide a suite of utilities for I/O operations on 'bdlbb::Blob'. : : 'bdlbb_pooledblobbufferfactory': : Provide a concrete implementation of 'bdlbb::BlobBufferFactory'. : : 'bdlbb_simpleblobbufferfactory': : Provide a simple implementation of 'bdlbb::BlobBufferFactory'.
