A StoreImpl implementation that uses MemoryStoreBuffer as its buffer to hold published messages in memory. More...
#include <MemoryPublishStore.hpp>
Public Member Functions | |
MemoryPublishStore (size_t blockPerRealloc_, bool errorOnPublishGap_=false) | |
Create a MemoryPublishStore with a specified initial capacity in bytes. More... | |
Public Member Functions inherited from AMPS::BlockPublishStore | |
amps_uint32_t | getBlockSize () |
Return the size left in a block for data when it has a header in it. More... | |
amps_uint32_t | getBlockDataSize () |
Return the size left in a block for data when it has a header in it. More... | |
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. | |
virtual amps_uint64_t | store (const Message &message_) |
Store a given message that will be delivered to AMPS. More... | |
amps_uint64_t | store (const Message &message_, bool assignSequence_) |
Store a given message that will be delivered to AMPS. More... | |
virtual void | discardUpTo (amps_uint64_t index_) |
Remove all messages with an index up to and including index_. More... | |
void | replay (StoreReplayer &replayer_) |
Replay all messages in the Store onto the given StoreReplayer. More... | |
bool | replaySingle (StoreReplayer &replayer_, amps_uint64_t index_) |
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_) |
Method to wait for the Store to discard everything that has been stored up to the point in time when flush is called. More... | |
amps_uint64_t | getLowestUnpersisted () const |
Get the oldest unpersisted message sequence in the store. More... | |
amps_uint64_t | getLastPersisted (void) |
Get the last persisted sequence number. More... | |
Public Member Functions inherited from AMPS::StoreImpl | |
StoreImpl (bool errorOnPublishGap_=false) | |
Default constructor. More... | |
virtual void | setResizeHandler (PublishStoreResizeHandler handler_, void *userData_) |
Set a handler to be called if the Store needs to resize in order to keep storing messages. More... | |
Additional Inherited Members | |
Public Types inherited from AMPS::BlockPublishStore | |
Static Public Member Functions inherited from AMPS::BlockPublishStore | |
static amps_uint32_t | getBlockHeaderSize () |
Block header is number of blocks, total length, sequence number, crc, next in chain offset. More... | |
static amps_uint32_t | getBlockChainHeaderSize () |
Block chain header is operation, command id length, correlation id length, expiration length, sow key length, topic length, sow delete flag, ack types. More... | |
Static Public Member Functions inherited from AMPS::StoreImpl | |
static size_t | getUnsetPosition () |
Method to return the value used to represent not found or unset. | |
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. |
