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, 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) ClientState 

func (q Keeper) ClientState(c context.Context, req *types.QueryClientStateRequest) (*types.QueryClientStateResponse, error)

ClientState implements the Query/ClientState gRPC method

func (Keeper) ClientStates 

func (q Keeper) ClientStates(c context.Context, req *types.QueryClientStatesRequest) (*types.QueryClientStatesResponse, error)

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 try to update the client with the new header if and only if the proposal passes. The localhost client is not allowed to be modified with a proposal.

func (Keeper) ConsensusState 

func (q Keeper) ConsensusState(c context.Context, req *types.QueryConsensusStateRequest) (*types.QueryConsensusStateResponse, error)

ConsensusState implements the Query/ConsensusState gRPC method

func (Keeper) ConsensusStates 

func (q Keeper) ConsensusStates(c context.Context, req *types.QueryConsensusStatesRequest) (*types.QueryConsensusStatesResponse, error)

ConsensusStates implements the Query/ConsensusStates gRPC method

func (Keeper) CreateClient 

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

CONTRACT: ClientState was constructed correctly from given initial consensusState

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) (genClients []types.IdentifiedClientState)

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

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) GetClientConsensusStateLTE 

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

GetClientConsensusStateLTE will get the latest ConsensusState of a particular client at the latest height less than or equal to the given height It will only search for heights within the same version

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) 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 version

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.

func (Keeper) Logger 

func (k Keeper) Logger(ctx sdk.Context) log.Logger

Logger returns a module-specific logger.

func (Keeper) MustMarshalClientState 

func (k Keeper) MustMarshalClientState(clientState exported.ClientState) []byte

MustMarshalClientState attempts to encode an ClientState object and returns the raw encoded bytes. It panics on error.

func (Keeper) MustMarshalConsensusState 

func (k Keeper) MustMarshalConsensusState(consensusState exported.ConsensusState) []byte

MustMarshalConsensusState attempts to encode an ConsensusState object and returns the raw encoded bytes. It panics on error.

func (Keeper) MustUnmarshalClientState 

func (k Keeper) MustUnmarshalClientState(bz []byte) exported.ClientState

MustUnmarshalClientState attempts to decode and return an ClientState object from raw encoded bytes. It panics on error.

func (Keeper) MustUnmarshalConsensusState 

func (k Keeper) MustUnmarshalConsensusState(bz []byte) exported.ConsensusState
