Member Function Documentation

checkTxPresence()

virtual std::optional<TxCacheStatusType> iroha::ametsuchi::BlockQuery::checkTxPresence ( const shared_model::crypto::Hash &  hash )

pure virtual

Synchronously checks whether transaction with given hash is present in any block

Parameters

hash	- transaction's hash

Returns

TxCacheStatusType which returns status (Committed, Rejected or Missing) of transaction if storage query was successful, null otherwise

Implemented in iroha::ametsuchi::BlockQueryBase.

getBlock()

virtual BlockResult iroha::ametsuchi::BlockQuery::getBlock ( shared_model::interface::types::HeightType  height )

pure virtual

Retrieve block with given height from block storage

Parameters

height

- height of a block to retrieve

Returns

block with given height

Implemented in iroha::ametsuchi::BlockQueryBase.

getTopBlockHeight()

virtual shared_model::interface::types::HeightType iroha::ametsuchi::BlockQuery::getTopBlockHeight ( )

pure virtual

Get height of the top block.

Returns

height

Implemented in iroha::ametsuchi::BlockQueryBase.

Here is the caller graph for this function:

reloadBlockstore()

virtual void iroha::ametsuchi::BlockQuery::reloadBlockstore ( )

pure virtual

Reloads blockstore

Implemented in iroha::ametsuchi::BlockQueryBase.
