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 (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.
