:mrdocs:

Create a pooled factory for allocating `BlobBuffer` objects of the specified `bufferSize`&period;

== Synopsis

Declared in `&lt;bdlbb&lowbar;pooledblobbufferfactory&period;h&gt;`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
PooledBlobBufferFactory(
    int bufferSize,
    xref:BloombergLP/bslma/Allocator.adoc[bslma::Allocator]* basicAllocator = 0);
----

== Description

Optionally specify a `growthStrategy` used to control the growth of internal memory chunks (from which memory blocks are dispensed)&period; If `growthStrategy` is not specified, geometric growth is used&period; If `growthStrategy` is specified, optionally specify a `maxBlocksPerChunk`, indicating the maximum number of blocks to be allocated at once when the underlying pool must be replenished&period; If `maxBlocksPerChunk` is not specified, an implementation&hyphen;defined value is used&period; If geometric growth is used, the chunk size grows starting at the value returned by `blockSize`, doubling in size until the size is exactly `blockSize() &ast; maxBlocksPerChunk`&period; If constant growth is used, the chunk size is always `maxBlocksPerChunk`&period; Optionally specify a `basicAllocator` used to supply memory&period; If `basicAllocator` is 0, the currently installed default allocator is used&period; The behavior is undefined unless `0 &lt; bufferSize`, and `1 &lt;&equals; maxBlocksPerChunk`&period;
