Detailed Description

Mutable storage is used apply blocks to the storage. Allows to query the world state view, transactions, and blocks.

MutableStoragePredicate

using iroha::ametsuchi::MutableStorage::MutableStoragePredicate = std::function<bool( std::shared_ptr<const shared_model::interface::Block>, const LedgerState &)>

Predicate type checking block Function parameters:

• Block - block to be checked
• LedgerState - the state of ledger on which the block is applied

Member Function Documentation

apply() [1/2]

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

pure virtual

Applies block without additional validation function

See also

apply(block, function)

Implemented in iroha::ametsuchi::MutableStorageImpl.

Here is the caller graph for this function:

apply() [2/2]

virtual bool iroha::ametsuchi::MutableStorage::apply ( rxcpp::observable< std::shared_ptr< shared_model::interface::Block >>  blocks, MutableStoragePredicate  predicate  )

pure virtual

Applies an observable of blocks to current mutable state using logic specified in function

Parameters

blocks	Blocks to be applied
predicate	Checks whether block is applicable prior to applying transactions

Returns

True if blocks were successfully applied, false otherwise.

Implemented in iroha::ametsuchi::MutableStorageImpl.

commit()

virtual expected::Result<MutableStorage::CommitResult, std::string> iroha::ametsuchi::MutableStorage::commit ( BlockStorage &  block_storage ) &&

pure virtual

Apply the local changes made to this MutableStorage to block_storage and the global WSV.

Implemented in iroha::ametsuchi::MutableStorageImpl.
