In-core container for BlobBuffer objects.
Declared in <bdlbb_blob.h>
class Blob;Blob is an in-core container for BlobBuffer objects. This class is exception-neutral with no guarantee of rollback: if an exception is thrown during the invocation of a method on a pre-existing instance, the container is left in a valid state, but its value is undefined. In no event is memory leaked.
