Functions

func BufferExecute

func BufferExecute(sysBuffer *SystemBufferContract, input []byte) ([]byte, error)

execute the system buffer contract

Types

type SystemBufferContract

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

SystemBufferContract used to cache the system contract data

func NewSystemBufferContract

func NewSystemBufferContract(db *repository.Repository) *SystemBufferContract

NewSystemBufferContract create a SystemBufferContract instance.

func (*SystemBufferContract) Address
