Detailed Description

template<class Tx, class NodeId>
class xrpl::DisputedTx< Tx, NodeId >

A transaction discovered to be in dispute during consensus.

During consensus, a DisputedTx is created when a transaction is discovered to be disputed. The object persists only as long as the dispute.

Undisputed transactions have no corresponding DisputedTx object.

Refer to Consensus for details on the template type requirements.

Template Parameters

Tx	The type for a transaction
NodeId	The type for a node identifier

		bool	votesYes )

nodiscard

Change a peer's vote.

Parameters

peer	Identifier of peer.
votesYes	Whether peer votes to include the disputed transaction.

Returns: bool Whether the peer changed its vote. (A new vote counts as a change.)

		bool	proposing,
		ConsensusParms const &	p )

Update our vote given progression of consensus.

Updates our vote on this disputed transaction based on our peers' votes and how far along consensus has proceeded.

Parameters

percentTime	Percentage progress through consensus, e.g. 50% through or 90%.
proposing	Whether we are proposing to our peers in this round.
p	Consensus parameters controlling thresholds for voting

Returns: Whether our vote changed
