Member Function Documentation

canHaveSupermajority()

virtual bool iroha::consensus::yac::SupermajorityChecker::canHaveSupermajority ( const VoteGroups &  votes, PeersNumberType  all  ) const

pure virtual

Check if supermajority is possible

Parameters

voted	- numbers of peers voted for each option
all	- number of peers in round

Returns

true, if reject

Implemented in iroha::consensus::yac::SupermajorityCheckerBft, and iroha::consensus::yac::SupermajorityCheckerCft.

hasSupermajority()

virtual bool iroha::consensus::yac::SupermajorityChecker::hasSupermajority ( PeersNumberType  current, PeersNumberType  all  ) const

pure virtual

Check if supermajority is achieved

Parameters

current	actual number of signatures
all	number of peers

Returns

true if supermajority is possible or false otherwise

Implemented in iroha::consensus::yac::SupermajorityCheckerBft, and iroha::consensus::yac::SupermajorityCheckerCft.

isTolerated()

virtual bool iroha::consensus::yac::SupermajorityChecker::isTolerated ( PeersNumberType  number, PeersNumberType  all  ) const

pure virtual

Check tolerance condition

Parameters

number	- voted peers
all	- number of all peers in network

Returns

true if the given number of peers is tolerated by the network

Implemented in iroha::consensus::yac::SupermajorityCheckerBft, and iroha::consensus::yac::SupermajorityCheckerCft.
