Types

type Keeper 

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

Keeper defines the IBC connection keeper

func NewKeeper 

func NewKeeper(aminoCdc *codec.Codec, cdc codec.Marshaler, key sdk.StoreKey, ck types.ClientKeeper) Keeper

ConnOpenAck relays acceptance of a connection open attempt from chain B back to chain A (this code is executed on chain A).

NOTE: Identifiers are checked on msg validation.

func (Keeper) ConnOpenConfirm 

func (k Keeper) ConnOpenConfirm(
	ctx sdk.Context,
	connectionID string,
	proofAck commitmentexported.Proof,
	proofHeight uint64,
) error

ConnOpenConfirm confirms opening of a connection on chain A to chain B, after which the connection is open on both chains (this code is executed on chain B).

NOTE: Identifiers are checked on msg validation.

func (Keeper) ConnOpenInit 

func (k Keeper) ConnOpenInit(
	ctx sdk.Context,
	connectionID,
	clientID string,
	counterparty types.Counterparty,
) error

ConnOpenInit initialises a connection attempt on chain A.

NOTE: Identifiers are checked on msg validation.

func (Keeper) ConnOpenTry 

func (k Keeper) ConnOpenTry(
	ctx sdk.Context,
	connectionID string,
	counterparty types.Counterparty,

	consensusHeight uint64,
) error

ConnOpenTry relays notice of a connection attempt on chain A to chain B (this code is executed on chain B).

NOTE:

  • Here chain A acts as the counterparty
  • Identifiers are checked on msg validation

func (Keeper) GetAllClientConnectionPaths 

func (k Keeper) GetAllClientConnectionPaths(ctx sdk.Context) []types.ConnectionPaths

GetAllClientConnectionPaths returns all stored clients connection id paths. It will ignore the clients that haven't initialized a connection handshake since no paths are stored.

func (Keeper) GetAllConnections 

func (k Keeper) GetAllConnections(ctx sdk.Context) (connections []types.ConnectionEnd)

GetAllConnections returns all stored ConnectionEnd objects.

func (Keeper) GetClientConnectionPaths 

func (k Keeper) GetClientConnectionPaths(ctx sdk.Context, clientID string) ([]string, bool)

GetClientConnectionPaths returns all the connection paths stored under a particular client

func (Keeper) GetCommitmentPrefix 

func (k Keeper) GetCommitmentPrefix() commitmentexported.Prefix

GetCommitmentPrefix returns the IBC connection store prefix as a commitment Prefix

func (Keeper) GetConnection 

func (k Keeper) GetConnection(ctx sdk.Context, connectionID string) (types.ConnectionEnd, bool)

GetConnection returns a connection with a particular identifier

func (Keeper) GetTimestampAtHeight 

func (k Keeper) GetTimestampAtHeight(ctx sdk.Context, connection types.ConnectionEnd, height uint64) (uint64, error)

GetTimestampAtHeight returns the timestamp in nanoseconds of the consensus state at the given height.

func (Keeper) IterateConnections 

func (k Keeper) IterateConnections(ctx sdk.Context, cb func(types.ConnectionEnd) bool)

IterateConnections provides an iterator over all ConnectionEnd objects. For each ConnectionEnd, 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) SetClientConnectionPaths 

func (k Keeper) SetClientConnectionPaths(ctx sdk.Context, clientID string, paths []string)

SetClientConnectionPaths sets the connections paths for client

func (Keeper) SetConnection 

func (k Keeper) SetConnection(ctx sdk.Context, connectionID string, connection types.ConnectionEnd)

SetConnection sets a connection to the store

func (Keeper) VerifyClientConsensusState 

func (k Keeper) VerifyClientConsensusState(
	ctx sdk.Context,
	connection exported.ConnectionI,
