Types

type ContractHandler

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

ContractHandler handles all interaction with smart contracts such as get/set/update it also captures all changes as deltas and only commit them when called so smart contract updates can be delayed until end of the tx execution

func NewContractHandler

func NewContractHandler(accounts *state.Accounts, restrictedDeploymentEnabled bool, authorizedAccounts []runtime.Address) *ContractHandler

func (*ContractHandler) Commit

func (h *ContractHandler) Commit() ([]programs.ContractUpdateKey, error)

func (*ContractHandler) GetContract

func (h *ContractHandler) GetContract(address runtime.Address, name string) (code []byte, err error)

func (*ContractHandler) GetContractNames

func (h *ContractHandler) GetContractNames(address runtime.Address) (names []string, err error)

func (*ContractHandler) HasUpdates

func (h *ContractHandler) HasUpdates() bool

func (*ContractHandler) RemoveContract

func (h *ContractHandler) RemoveContract(address runtime.Address, name string, signingAccounts []runtime.Address) (err error)

func (*ContractHandler) Rollback

func (h *ContractHandler) Rollback() error

func (*ContractHandler) SetContract

func (h *ContractHandler) SetContract(address runtime.Address, name string, code []byte, signingAccounts []runtime.Address) (err error)

func (*ContractHandler) UpdateKeys

func (h *ContractHandler) UpdateKeys() []programs.ContractUpdateKey

type ProgramsHandler

type ProgramsHandler struct {
	Programs *programs.Programs
	// contains filtered or unexported fields
}

ProgramsHandler manages operations using Programs storage. It's separation of concern for hostEnv Cadence contract guarantees that Get/Set methods will be called in a LIFO manner, so we use stack based approach here. During successful execution stack should be cleared naturally, making cleanup method essentially no-op. But if something goes wrong, all nested views must be merged in order to make sure they are recorded

func NewProgramsHandler

func NewProgramsHandler(programs *programs.Programs, stateHolder *state.StateHolder) *ProgramsHandler

func (*ProgramsHandler) Cleanup

func (h *ProgramsHandler) Cleanup() error

func (*ProgramsHandler) Get

func (h *ProgramsHandler) Get(location common.Location) (*interpreter.Program, bool)

func (*ProgramsHandler) Set

func (h *ProgramsHandler) Set(location common.Location, program *interpreter.Program) error
