Functions

func EmitWriteErrorAcknowledgementEvent

func EmitWriteErrorAcknowledgementEvent(ctx sdk.Context, packet exported.PacketI, err error)

EmitWriteErrorAcknowledgementEvent emits an event signalling an error acknowledgement and including the error details

Types

type Keeper

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

Keeper defines the IBC interchain query host keeper

func NewKeeper

func NewKeeper(
	cdc codec.BinaryCodec, key storetypes.StoreKey, paramSpace paramtypes.Subspace,
	ics4Wrapper types.ICS4Wrapper, channelKeeper types.ChannelKeeper, portKeeper types.PortKeeper,
	scopedKeeper capabilitykeeper.ScopedKeeper, queryRouter *baseapp.GRPCQueryRouter,
) Keeper

NewKeeper creates a new interchain query Keeper instance

func (Keeper) AuthenticateCapability

func (k Keeper) AuthenticateCapability(ctx sdk.Context, cap *capabilitytypes.Capability, name string) bool

AuthenticateCapability wraps the scopedKeeper's AuthenticateCapability function

func (Keeper) BindPort

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

BindPort stores the provided portID and binds to it, returning the associated capability

func (Keeper) ClaimCapability

func (k Keeper) ClaimCapability(ctx sdk.Context, cap *capabilitytypes.Capability, name string) error

ClaimCapability wraps the scopedKeeper's ClaimCapability function

func (Keeper) ExportGenesis

func (k Keeper) ExportGenesis(ctx sdk.Context) *types.GenesisState

ExportGenesis exports icq module's portID and denom trace info into its genesis state.

func (Keeper) GetAllowQueries

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

GetAllowQueries retrieves the host enabled query paths 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) GetParams

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

GetParams returns the total set of the parameters.

func (Keeper) GetPort

func (k Keeper) GetPort(ctx sdk.Context) string

GetPort returns the portID for the transfer module. Used in ExportGenesis

func (Keeper) InitGenesis

func (k Keeper) InitGenesis(ctx sdk.Context, state types.GenesisState)

InitGenesis initializes the icq state and binds to PortID.

func (Keeper) IsBound

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

IsBound checks if the interchain query 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 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) OnRecvPacket

func (k Keeper) OnRecvPacket(ctx sdk.Context, packet channeltypes.Packet) ([]byte, error)

OnRecvPacket handles a given interchain queries packet on a destination host chain. If the transaction is successfully executed, the transaction response bytes will be returned.

func (Keeper) Params

func (q Keeper) Params(c context.Context, _ *types.QueryParamsRequest) (*types.QueryParamsResponse, error)

Params implements the Query/Params gRPC method

func (Keeper) SetParams

func (k Keeper) SetParams(ctx sdk.Context, params types.Params)

SetParams sets the total set of the parameters.

func (Keeper) SetPort

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

SetPort sets the portID for the transfer module. Used in InitGenesis
