void BlockDisconnected(const std::shared_ptr< const CBlock > &pblock, const CBlockIndex *pindexDisconnected) override
Notifies listeners of a block being disconnected.
void TransactionAddedToMempool(const CTransactionRef &tx, uint64_t mempool_sequence) override
Notifies listeners of a transaction having been added to mempool.
std::list< std::unique_ptr< CZMQAbstractNotifier > > notifiers
MemPoolRemovalReason
Reason why a transaction was removed from the mempool, this is passed to the notification signal...
Definition: txmempool.h:392
Implement this to subscribe to events generated in validation.
void TransactionRemovedFromMempool(const CTransactionRef &tx, MemPoolRemovalReason reason, uint64_t mempool_sequence) override
Notifies listeners of a transaction leaving mempool.

void BlockConnected(const std::shared_ptr< const CBlock > &pblock, const CBlockIndex *pindexConnected) override
Notifies listeners of a block being connected.
void UpdatedBlockTip(const CBlockIndex *pindexNew, const CBlockIndex *pindexFork, bool fInitialDownload) override
Notifies listeners when the block chain tip advances.
The block chain is a tree shaped structure starting with the genesis block at the root...
