type Context ¶

type Context struct {
	ContractAddress common.Address
	Code            []byte
}

Context describe smart contract execute context struct

type ContextRef ¶

type ContextRef interface {
	PushContext(context *Context)
	CurrentContext() *Context
	CallingContext() *Context
	EntryContext() *Context
	PopContext()
	CheckWitness(address common.Address) bool
	PushNotifications(notifications []*event.NotifyEventInfo)
	NewExecuteEngine(code []byte, txtype types.TransactionType) (Engine, error)
	CheckUseGas(gas uint64) bool
	CheckExecStep() bool
}

ContextRef is a interface of smart context when need call a contract, push current context to smart contract contexts when execute smart contract finish, pop current context from smart contract contexts when need to check authorization, use CheckWitness when smart contract execute trigger event, use PushNotifications push it to smart contract notifications when need to invoke a smart contract, use AppCall to invoke it

type Engine ¶

type Engine interface {
	Invoke() (interface{}, error)
}
