Declared in <bdlbb_pooledblobbufferfactory.h>

Create a pooled factory for allocating BlobBuffer objects of the specified bufferSize. Optionally specify a growthStrategy used to control the growth of internal memory chunks (from which memory blocks are dispensed). If growthStrategy is not specified, geometric growth is used. 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. If maxBlocksPerChunk is not specified, an implementation‐defined value is used. 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() * maxBlocksPerChunk. If constant growth is used, the chunk size is always maxBlocksPerChunk. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used. The behavior is undefined unless 0 < bufferSize, and 1 <= maxBlocksPerChunk.

    int bufferSize,
    bslma::Allocator* basicAllocator = 0);
