| BlockPublishStore (Buffer *buffer_, amps_uint32_t blocksPerRealloc_=1000, bool isFile_=false, bool errorOnPublishGap_=false, amps_uint32_t blockSize_=DEFAULT_BLOCK_SIZE) | |
| Create a BlockPublishStore using buffer_, that grows by blocksPerRealloc_ blocks when it must grow. More... | |
| virtual | ~BlockPublishStore () |
| Destructor that cleans up the buffer and other associated memory. | |

| Replay one message in the Store onto the given StoreReplayer. More... | |
| size_t | unpersistedCount () const |
| Method to return the count of messages that currently in the Store because they have not been discarded, presumably because AMPS has not yet acknowledged them. More... | |
| virtual void | flush (long timeout_) |

| static amps_uint64_t | getUnsetSequence () |
| Method to return the value used to represent no such sequence. | |
A StoreImpl implementation that uses MemoryStoreBuffer as its buffer to hold published messages in memory.
This store does not persist the published messages, so this store cannot be used to guarantee message publication if the application restarts.

inline |
Create a MemoryPublishStore with a specified initial capacity in bytes.
| blockPerRealloc_ | The number of blocks to grow by when capacity has been exceeded. |
| errorOnPublishGap_ | If true, PublishStoreGapException can be thrown by the store if the client logs onto a server that appears to be missing messages no longer held in the store. |
