Types

type Keeper

type Keeper struct {
	// contains filtered or unexported fields
}

Keeper represents a type that grants read and write permissions to any client state information

func NewKeeper

func NewKeeper(cdc codec.BinaryMarshaler, key sdk.StoreKey, paramSpace paramtypes.Subspace, sk types.StakingKeeper) Keeper

NewKeeper creates a new NewKeeper instance

func (Keeper) CheckMisbehaviourAndUpdateState

func (k Keeper) CheckMisbehaviourAndUpdateState(ctx sdk.Context, misbehaviour exported.Misbehaviour) error

CheckMisbehaviourAndUpdateState checks for client misbehaviour and freezes the client if so.

func (Keeper) ClientParams

ClientParams implements the Query/ClientParams gRPC method

func (Keeper) ClientState

ClientState implements the Query/ClientState gRPC method

func (Keeper) ClientStates

ClientStates implements the Query/ClientStates gRPC method

func (Keeper) ClientStore

func (k Keeper) ClientStore(ctx sdk.Context, clientID string) sdk.KVStore

ClientStore returns isolated prefix store for each client so they can read/write in separate namespace without being able to read/write other client's data

func (Keeper) ClientUpdateProposal

func (k Keeper) ClientUpdateProposal(ctx sdk.Context, p *types.ClientUpdateProposal) error

ClientUpdateProposal will retrieve the subject and substitute client. The initial height must be greater than the latest height of the subject client. A callback will occur to the subject client state with the client prefixed store being provided for both the subject and the substitute client. The localhost client is not allowed to be modified with a proposal. The IBC client implementations are responsible for validating the parameters of the subtitute (enusring they match the subject's parameters) as well as copying the necessary consensus states from the subtitute to the subject client store.

func (Keeper) ConsensusState

ConsensusState implements the Query/ConsensusState gRPC method

func (Keeper) ConsensusStates

ConsensusStates implements the Query/ConsensusStates gRPC method

func (Keeper) CreateClient

func (k Keeper) CreateClient(
	ctx sdk.Context, clientState exported.ClientState, consensusState exported.ConsensusState,
) (string, error)

CreateClient creates a new client state and populates it with a given consensus state as defined in https://github.com/cosmos/ics/tree/master/spec/ics-002-client-semantics#create

func (k Keeper) GenerateClientIdentifier(ctx sdk.Context, clientType string) string

GenerateClientIdentifier returns the next client identifier.

func (Keeper) GetAllClientMetadata

func (k Keeper) GetAllClientMetadata(ctx sdk.Context, genClients []types.IdentifiedClientState) ([]types.IdentifiedGenesisMetadata, error)

GetAllClientMetadata will take a list of IdentifiedClientState and return a list of IdentifiedGenesisMetadata necessary for exporting and importing client metadata into the client store.

func (Keeper) GetAllClients

func (k Keeper) GetAllClients(ctx sdk.Context) (states []exported.ClientState)

GetAllClients returns all stored light client State objects.

func (Keeper) GetAllConsensusStates

func (k Keeper) GetAllConsensusStates(ctx sdk.Context) types.ClientsConsensusStates

GetAllConsensusStates returns all stored client consensus states.

func (Keeper) GetAllGenesisClients

func (k Keeper) GetAllGenesisClients(ctx sdk.Context) types.IdentifiedClientStates

GetAllGenesisClients returns all the clients in state with their client ids returned as IdentifiedClientState

func (k Keeper) GetAllowedClients(ctx sdk.Context) []string

GetAllowedClients retrieves the receive enabled boolean from the paramstore

func (Keeper) GetClientConsensusState

func (k Keeper) GetClientConsensusState(ctx sdk.Context, clientID string, height exported.Height) (exported.ConsensusState, bool)

GetClientConsensusState gets the stored consensus state from a client at a given height.

func (Keeper) GetClientState

func (k Keeper) GetClientState(ctx sdk.Context, clientID string) (exported.ClientState, bool)

GetClientState gets a particular client from the store

func (Keeper) GetLatestClientConsensusState

func (k Keeper) GetLatestClientConsensusState(ctx sdk.Context, clientID string) (exported.ConsensusState, bool)

GetLatestClientConsensusState gets the latest ConsensusState stored for a given client

func (Keeper) GetNextClientSequence

func (k Keeper) GetNextClientSequence(ctx sdk.Context) uint64

GetNextClientSequence gets the next client sequence from the store.

func (Keeper) GetParams

func (k Keeper) GetParams(ctx sdk.Context) types.Params

GetParams returns the total set of ibc-transfer parameters.

func (Keeper) GetSelfConsensusState

func (k Keeper) GetSelfConsensusState(ctx sdk.Context, height exported.Height) (exported.ConsensusState, bool)

GetSelfConsensusState introspects the (self) past historical info at a given height and returns the expected consensus state at that height. For now, can only retrieve self consensus states for the current revision

func (Keeper) HasClientConsensusState

func (k Keeper) HasClientConsensusState(ctx sdk.Context, clientID string, height exported.Height) bool

HasClientConsensusState returns if keeper has a ConsensusState for a particular client at the given height

func (Keeper) IterateClients

func (k Keeper) IterateClients(ctx sdk.Context, cb func(clientID string, cs exported.ClientState) bool)

IterateClients provides an iterator over all stored light client State objects. For each State object, cb will be called. If the cb returns true, the iterator will close and stop.

func (Keeper) IterateConsensusStates

func (k Keeper) IterateConsensusStates(ctx sdk.Context, cb func(clientID string, cs types.ConsensusStateWithHeight) bool)

IterateConsensusStates provides an iterator over all stored consensus states. objects. For each State object, cb will be called. If the cb returns true, the iterator will close and stop.
