Namespace for blob and blob‐buffer components.

== Types

[cols="1,4"]
|===
| Name| Description
| xref:BloombergLP/bdlbb/Blob.adoc[`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.
| xref:BloombergLP/bdlbb/BlobBuffer.adoc[`BlobBuffer`] 
| `BlobBuffer` is a simple in‐core representation of a shared buffer. 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.
| xref:BloombergLP/bdlbb/BlobBufferFactory.adoc[`BlobBufferFactory`] 
| This class defines a base‐level protocol for a `BlobBuffer` factory.
| xref:BloombergLP/bdlbb/BlobUtil.adoc[`BlobUtil`] 
| This `struct` is a namespace for a collection of static methods used for manipulating and accessing `Blob` objects.
| xref:BloombergLP/bdlbb/BlobUtilAsciiDumper.adoc[`BlobUtilAsciiDumper`] 
| Utility for ascii dumping a blob to standard output streams. This class has `operator<<` defined for it, so it can be used, for example, in `ball` logs.
| xref:BloombergLP/bdlbb/BlobUtilHexDumper.adoc[`BlobUtilHexDumper`] 
| Utility for hex dumping a blob to standard output streams. This class has `operator<<` defined for it, so it can be used, for example, in `ball` logs.
| xref:BloombergLP/bdlbb/InBlobStreamBuf.adoc[`InBlobStreamBuf`] 
| This class implements the input functionality of the `basic_streambuf` protocol, using a client‐supplied `bdlbb::Blob`.
| xref:BloombergLP/bdlbb/OutBlobStreamBuf.adoc[`OutBlobStreamBuf`] 
| This class implements the output functionality of the `basic_streambuf` protocol, using a client‐supplied `bdlbb::Blob`.
| xref:BloombergLP/bdlbb/PooledBlobBufferFactory.adoc[`PooledBlobBufferFactory`] 
| This class implements the `BlobBufferFactory` protocol and provides a mechanism for allocating `BlobBuffer` objects of a fixed size passed at construction.
| xref:BloombergLP/bdlbb/SimpleBlobBufferFactory.adoc[`SimpleBlobBufferFactory`] 
| This `class` declares an implementation of `BlobBufferFactory` where each segment loaded to a `BlobBuffer` is created with a separate calls to the allocator specified at construction, or the default allocator is no allocator was specified.
