func (k Keeper) GetActiveChannelID(ctx sdk.Context, connectionID, portID string) (string, bool)

GetActiveChannelID retrieves the active channelID from the store keyed by the provided connectionID and portID

func (Keeper) GetAllActiveChannels 

func (k Keeper) GetAllActiveChannels(ctx sdk.Context) []genesistypes.ActiveChannel

GetAllActiveChannels returns a list of all active interchain accounts host channels and their associated connection and port identifiers

func (Keeper) GetAllInterchainAccounts 

func (k Keeper) GetAllInterchainAccounts(ctx sdk.Context) []genesistypes.RegisteredInterchainAccount

GetAllInterchainAccounts returns a list of all registered interchain account addresses and their associated connection and controller port identifiers

func (Keeper) GetAllowMessages 

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

GetAllowMessages retrieves the host enabled msg types from the paramstore

func (Keeper) GetAppVersion 

func (k Keeper) GetAppVersion(ctx sdk.Context, portID, channelID string) (string, bool)

GetAppVersion calls the ICS4Wrapper GetAppVersion function.

func (Keeper) GetInterchainAccountAddress 

func (k Keeper) GetInterchainAccountAddress(ctx sdk.Context, connectionID, portID string) (string, bool)

GetInterchainAccountAddress retrieves the InterchainAccount address from the store associated with the provided connectionID and portID

func (Keeper) GetOpenActiveChannel 

func (k Keeper) GetOpenActiveChannel(ctx sdk.Context, connectionID, portID string) (string, bool)

GetOpenActiveChannel retrieves the active channelID from the store, keyed by the provided connectionID and portID & checks if the channel in question is in state OPEN

func (Keeper) GetParams 

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

GetParams returns the total set of the host submodule parameters.

func (Keeper) IsActiveChannel 

func (k Keeper) IsActiveChannel(ctx sdk.Context, connectionID, portID string) bool

IsActiveChannel returns true if there exists an active channel for the provided connectionID and portID, otherwise false

func (Keeper) IsBound 

func (k Keeper) IsBound(ctx sdk.Context, portID string) bool

IsBound checks if the interchain account host module is already bound to the desired port

func (Keeper) IsHostEnabled 

func (k Keeper) IsHostEnabled(ctx sdk.Context) bool

IsHostEnabled retrieves the host enabled boolean from the paramstore. True is returned if the host submodule is enabled.

func (Keeper) Logger 

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

Logger returns the application logger, scoped to the associated module

func (Keeper) OnChanCloseConfirm 

func (k Keeper) OnChanCloseConfirm(
	ctx sdk.Context,
	portID,
	channelID string,
) error

OnChanCloseConfirm removes the active channel stored in state

func (Keeper) OnChanOpenConfirm 

func (k Keeper) OnChanOpenConfirm(
	ctx sdk.Context,
	portID,
	channelID string,
) error

OnChanOpenConfirm completes the handshake process by setting the active channel in state on the host chain

func (Keeper) OnChanOpenTry 

func (k Keeper) OnChanOpenTry(
	ctx sdk.Context,
	order channeltypes.Order,
	connectionHops []string,
	portID,
	channelID string,
	chanCap *capabilitytypes.Capability,
