public LinearState extends ContractState
A state that evolves by superseding itself, all of which share the common "linearId".
This simplifies the job of tracking the current version of certain types of state in e.g. a vault.
@NotNull UniqueIdentifier getLinearId()
Unique id shared by all LinearState states throughout history within the vaults of all parties. Verify methods should check that one input and one output share the id in a transaction, except at issuance/termination.
