validTransition

Encodes application-specific rules for a particular ForceMove-compliant state channel.

function validTransition(struct IForceMoveApp.VariablePart a, struct IForceMoveApp.VariablePart b, uint48 turnNumB, uint256 nParticipants) external pure

returns(bool)

Returns

true if the transition conforms to this application's rules, false otherwise

Arguments

Name	Type	Description
a	struct IForceMoveApp.VariablePart	State being transitioned from.
b	struct IForceMoveApp.VariablePart	State being transitioned to.
turnNumB	uint48	Turn number being transitioned to.
nParticipants	uint256	Number of participants in this state channel.
