Class: ActiveProtection

client.ActiveProtection

A State instance is a state in the "state machine" sense. It comes with some behavior and state transition methods. A state transition method returns an instance of the next state given the executed operation, which discards current object.

This class should be extended by client class. It provides method enabling the client class to query if it was already discarded or not as well as methods actually discarding the state.

Accessors

discarded

• get discarded(): boolean

Returns

boolean

Description

True if this state was discarded

Inherited from

State.discarded

protectionParameters

• get protectionParameters(): ProtectionParameters

Returns

ProtectionParameters

Methods

discard

▸ discard(next): void

Parameters

Name	Type
next	undefined | State

Returns

void

Description

Discards current state. One must discard the state only if the state transition was successfully executed. It may be safer to use discardOnSuccess.

Inherited from

State.discard

Defined in

packages/client/src/State.ts:43

discardOnSuccess

▸ discardOnSuccess<T, U>(action): Promise<U>

Type parameters

Name	Type
T	extends State
U	extends State = T

Parameters

Name	Type	Description
action	(current: T) => Promise<U>	The state transition logic producing next state

Returns

Promise<U>

Next state if state transition logic execution did not throw

Descripiton

Discards current state only if given state transition logic executed successfully (i.e. without throwing an error).

Inherited from

State.discardOnSuccess

Defined in

packages/client/src/State.ts:55

---

ensureCurrent

▸ ensureCurrent(): void

Returns

void

Description

Throws an error if this state was discarded. This should be called by all public methods of client class.

Inherited from

State.ensureCurrent

Defined in

packages/client/src/State.ts:32

---

finalizeOnSuccess

▸ finalizeOnSuccess<T>(action): Promise<void>

Type parameters

Name	Type
T	extends State

Parameters

Name	Type	Description
action	(current: T) => Promise<void>	The state transition logic producing next state

Returns

Promise<void>

Next state if state transition logic execution did not throw

Descripiton

Finalizes (i.e. replaces with no new state) current state only if given state transition logic executed successfully (i.e. without throwing an error).

Inherited from

State.finalizeOnSuccess

Defined in

packages/client/src/State.ts:117

---

getCurrentState

▸ getCurrentState(): undefined | State

Returns

undefined | State

This state if not discareded or the current state or undefined when there is no current state.

Description

If the state has been discarded, provides the replacing current state if any.

Inherited from

State.getCurrentState

Defined in

packages/client/src/State.ts:90

getCurrentStateOrThrow

▸ getCurrentStateOrThrow(): State

Returns

State

Inherited from

isFullyReady

▸ isFullyReady(): boolean

Returns

boolean

refresh

▸ refresh(): Promise<ActiveProtection>

Returns

Promise<ActiveProtection>

Implementation of

WithRefresh.refresh

Defined in

syncDiscardOnSuccess

▸ syncDiscardOnSuccess<T, U>(action): U

Type parameters

Name	Type
T	extends State
U	extends State = T

Parameters

Name	Type	Description
action	(current: T) => U	The state transition logic producing next state

Returns

U

Next state if state transition logic execution did not throw

Descripiton

Same as discardOnSuccess but with a synchronous action.

Inherited from

State.syncDiscardOnSuccess

Defined in

---

vaultState

▸ vaultState(): Promise<VaultState>

Returns

Promise<VaultState>

Defined in
