| Destroy this factory. This operation releases all `BlobBuffer` objects allocated via this factory.
| xref:BloombergLP/bdlbb/PooledBlobBufferFactory/allocate.adoc[`allocate`]  [.small]#[virtual]#
| Allocate a new buffer with the buffer size specified at construction and load it into the specified `buffer`. Note that destruction of the `bdlbb::PooledBlobBufferFactory` object releases all `BlobBuffer` objects allocated via this factory.
