	// contains filtered or unexported fields
}

Hook uses levelDB to store the latest price of standard price reference.

func NewHook

func NewHook(cdc *codec.Codec, oracleKeeper keeper.Keeper, oids []types.OracleScriptID, priceDBDir string) *Hook

NewHook creates a price hook instance that will be added in Band App.

func (*Hook) AfterBeginBlock

func (h *Hook) AfterBeginBlock(ctx sdk.Context, req abci.RequestBeginBlock, res abci.ResponseBeginBlock)

AfterBeginBlock specify actions need to do after begin block period (app.Hook interface).

func (*Hook) AfterDeliverTx

func (h *Hook) AfterDeliverTx(ctx sdk.Context, req abci.RequestDeliverTx, res abci.ResponseDeliverTx)

AfterDeliverTx specify actions need to do after transaction has been processed (app.Hook interface).

func (*Hook) AfterEndBlock

func (h *Hook) AfterEndBlock(ctx sdk.Context, req abci.RequestEndBlock, res abci.ResponseEndBlock)
