Member Function Documentation

clear()

virtual void iroha::ametsuchi::BlockStorage::clear ( )

pure virtual

Clears the contents of storage

Implemented in iroha::ametsuchi::PostgresBlockStorage, iroha::ametsuchi::FlatFileBlockStorage, and iroha::ametsuchi::InMemoryBlockStorage.

fetch()

virtual boost::optional<std::unique_ptr<shared_model::interface::Block> > iroha::ametsuchi::BlockStorage::fetch ( shared_model::interface::types::HeightType  height ) const

pure virtual

Get block with given height

Returns

block if exists, boost::none otherwise

Implemented in iroha::ametsuchi::PostgresBlockStorage, iroha::ametsuchi::FlatFileBlockStorage, and iroha::ametsuchi::InMemoryBlockStorage.

Here is the caller graph for this function:

forEach()

virtual expected::Result<void, std::string> iroha::ametsuchi::BlockStorage::forEach ( FunctionType  function ) const

pure virtual

Iterates through all the stored blocks

Implemented in iroha::ametsuchi::PostgresBlockStorage, iroha::ametsuchi::FlatFileBlockStorage, and iroha::ametsuchi::InMemoryBlockStorage.

insert()

virtual bool iroha::ametsuchi::BlockStorage::insert ( std::shared_ptr< const shared_model::interface::Block >  block )

pure virtual

Append block, if the storage doesn't already contain the same block

Returns

true if inserted successfully, false otherwise

Implemented in iroha::ametsuchi::PostgresBlockStorage, iroha::ametsuchi::FlatFileBlockStorage, and iroha::ametsuchi::InMemoryBlockStorage.

reload()

virtual void iroha::ametsuchi::BlockStorage::reload ( )

pure virtual

Reloads blocks in case their were modified externally

Implemented in iroha::ametsuchi::PostgresBlockStorage, iroha::ametsuchi::FlatFileBlockStorage, and iroha::ametsuchi::InMemoryBlockStorage.

Here is the caller graph for this function:

size()

virtual size_t iroha::ametsuchi::BlockStorage::size ( ) const

pure virtual

Returns the size of the storage

Implemented in iroha::ametsuchi::PostgresBlockStorage, iroha::ametsuchi::FlatFileBlockStorage, and iroha::ametsuchi::InMemoryBlockStorage.

Here is the caller graph for this function:
