Types

type BaseKeeper 

type BaseKeeper struct {
	BaseSendKeeper
	// contains filtered or unexported fields
}

BaseKeeper manages transfers between accounts. It implements the Keeper interface.

func NewBaseKeeper 

func NewBaseKeeper(
	ak types.AccountKeeper, paramSpace params.Subspace, blacklistedAddrs map[string]bool,
) BaseKeeper

NewBaseKeeper returns a new BaseKeeper

func NewBaseKeeperWithMarshal 

func NewBaseKeeperWithMarshal(ak types.AccountKeeper, marshal *codec.CodecProxy, paramSpace params.Subspace, blacklistedAddrs map[string]bool,
) BaseKeeper

func (BaseKeeper) DelegateCoins 

func (keeper BaseKeeper) DelegateCoins(ctx sdk.Context, delegatorAddr, moduleAccAddr sdk.AccAddress, amt sdk.Coins) (err error)

DelegateCoins performs delegation by deducting amt coins from an account with address addr. For vesting accounts, delegations amounts are tracked for both vesting and vested coins. The coins are then transferred from the delegator address to a ModuleAccount address. If any of the delegation amounts are negative, an error is returned.

func (*BaseKeeper) SetInnerTxKeeper 

func (k *BaseKeeper) SetInnerTxKeeper(keeper innertx.InnerTxKeeper)

SetInnerTxKeeper set innerTxKeeper

func (BaseKeeper) UndelegateCoins 

func (keeper BaseKeeper) UndelegateCoins(ctx sdk.Context, moduleAccAddr, delegatorAddr sdk.AccAddress, amt sdk.Coins) (err error)

UndelegateCoins performs undelegation by crediting amt coins to an account with address addr. For vesting accounts, undelegation amounts are tracked for both vesting and vested coins. The coins are then transferred from a ModuleAccount address to the delegator address. If any of the undelegation amounts are negative, an error is returned.

type BaseSendKeeper 

type BaseSendKeeper struct {
	BaseViewKeeper
	// contains filtered or unexported fields
}

BaseSendKeeper only allows transfers between accounts without the possibility of creating coins. It implements the SendKeeper interface.

func NewBaseSendKeeper 

func NewBaseSendKeeper(
	ak types.AccountKeeper, paramSpace params.Subspace, blacklistedAddrs map[string]bool,
) BaseSendKeeper

NewBaseSendKeeper returns a new BaseSendKeeper.

func (BaseSendKeeper) AddCoins 

func (keeper BaseSendKeeper) AddCoins(ctx sdk.Context, addr sdk.AccAddress, amt sdk.Coins) (sdk.Coins, error)

AddCoins adds amt to the coins at the addr.

func (BaseSendKeeper) BlacklistedAddr 

func (keeper BaseSendKeeper) BlacklistedAddr(addr sdk.AccAddress) bool

BlacklistedAddr checks if a given address is blacklisted (i.e restricted from receiving funds)

func (BaseSendKeeper) GetInnerTxKeeper 

func (k BaseSendKeeper) GetInnerTxKeeper() innertx.InnerTxKeeper

func (BaseSendKeeper) GetSendEnabled 

func (keeper BaseSendKeeper) GetSendEnabled(ctx sdk.Context) bool

GetSendEnabled returns the current SendEnabled

func (BaseSendKeeper) InputOutputCoins 

func (keeper BaseSendKeeper) InputOutputCoins(ctx sdk.Context, inputs []types.Input, outputs []types.Output) (err error)

InputOutputCoins handles a list of inputs and outputs

func (BaseSendKeeper) SendCoins 

func (keeper BaseSendKeeper) SendCoins(ctx sdk.Context, fromAddr sdk.AccAddress, toAddr sdk.AccAddress, amt sdk.Coins) (err error)

SendCoins moves coins from one account to another

func (BaseSendKeeper) SetCoins 

func (keeper BaseSendKeeper) SetCoins(ctx sdk.Context, addr sdk.AccAddress, amt sdk.Coins) error

SetCoins sets the coins at the addr.

func (*BaseSendKeeper) SetInnerTxKeeper 

func (k *BaseSendKeeper) SetInnerTxKeeper(keeper innertx.InnerTxKeeper)

func (BaseSendKeeper) SetSendEnabled 

func (keeper BaseSendKeeper) SetSendEnabled(ctx sdk.Context, enabled bool)

SetSendEnabled sets the send enabled

func (BaseSendKeeper) SubtractCoins 

func (keeper BaseSendKeeper) SubtractCoins(ctx sdk.Context, addr sdk.AccAddress, amt sdk.Coins) (sdk.Coins, error)

SubtractCoins subtracts amt from the coins at the addr.

CONTRACT: If the account is a vesting account, the amount has to be spendable.

type BaseViewKeeper 

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

BaseViewKeeper implements a read only keeper implementation of ViewKeeper.

func NewBaseViewKeeper 

func NewBaseViewKeeper(ak types.AccountKeeper) BaseViewKeeper

NewBaseViewKeeper returns a new BaseViewKeeper.

func (BaseViewKeeper) GetCoins 

func (keeper BaseViewKeeper) GetCoins(ctx sdk.Context, addr sdk.AccAddress) sdk.Coins

GetCoins returns the coins at the addr.

func (BaseViewKeeper) HasCoins 

func (keeper BaseViewKeeper) HasCoins(ctx sdk.Context, addr sdk.AccAddress, amt sdk.Coins) bool

HasCoins returns whether or not an account has at least amt coins.

func (BaseViewKeeper) Logger 

func (keeper BaseViewKeeper) Logger(ctx sdk.Context) log.Logger

Logger returns a module-specific logger.

type Keeper 

type Keeper interface {
	SendKeeper

	DelegateCoins(ctx sdk.Context, delegatorAddr, moduleAccAddr sdk.AccAddress, amt sdk.Coins) error
