InMemoryClientStorage class

An in-memory storage solution for the ClientStorageInterface. This is used by the tests and example but real applications would benefit from persistant storage.

Methods

addNewFrostKey(FrostKeyWithDetails newKey) → Future<void>
Add new key with details to storage
override
addOrReplaceAck(SignedDkgAck ack) → Future<void>
Adds the acknowledgement of a FROST key for a participant, including for self. May update an existing ACK
override
addRejectedSigsRequest(SignaturesRequestId id, FinalExpirable expirable) → Future<void>
Add the ID of a signatures request that was rejected. This may be removed when expirable expires or by removeRejectionOfSigsRequest.
override
addSignaturesNonces(SignaturesRequestId id, SignaturesNonces nonces, int capacity) → Future<void>
Stores the nonces for the presignatures of a request given by id. Each nonce is mapped by the signature index in the request.
override
loadKeys() → Future<Set<FrostKeyWithDetails>>
Load the key details including SignedDkgAcks.
override
loadRejectedSigsRequests() → Future<Map<SignaturesRequestId, FinalExpirable>>
Loads the IDs of all of the signatures requests that were rejected by the client
override
loadSigNonces() → Future<Map<SignaturesRequestId, SignaturesNonces>>
For every non-expired signature request, this should return a map from the
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeRejectionOfSigsRequest(SignaturesRequestId id) → Future<void>
Removes the ID of a signatures request that is no longer rejected.
override
removeSigsRequest(SignaturesRequestId id) → Future<void>
Remove all data (rejection and/or nonces) for a signatures request
override
toString() → String
A string representation of this object.
inherited
waitForKeyWithName(String name, int expAcks) → Future<FrostKeyWithDetails>
Waits for a key to be created and receive a number of ACKs. Must only be used once at a time.

Operators

operator ==(Object other) → bool
The equality operator.
