Wallet

abstract class Wallet

A wallet (name may be temporary) wraps a set of states that are useful for us to keep track of, for instance, because we own them. This class represents an immutable, stable state of a wallet: it is guaranteed not to change out from underneath you, even though the canonical currently-best-known wallet may change as we learn about new transactions from our peers and generate new transactions that consume states ourselves.

This absract class has no references to Cash contracts.





Types

Update data class Update

Represents an update observed by the Wallet that will be notified to observers. Include the StateRefs of transaction outputs that were consumed (inputs) and the ContractStates produced (outputs) to/by the transaction or transactions observed and the Wallet.
