Class: Mesh

The main class for this package. Has methods for receiving order events and sending orders through the 0x Mesh network.

Hierarchy

• Mesh

Constructors

constructer

+ new Mesh(config: Config): Mesh

Defined in index.ts:565

Instantiates a new Mesh instance.

Parameters:

Name	Type	Description
config	Config	Configuration options for Mesh

Returns: Mesh

An instance of Mesh

Methods

addOrdersAsync

▸ addOrdersAsync(orders: SignedOrder[], pinned: boolean): Promise‹ValidationResults›

Defined in index.ts:639

Validates and adds the given orders to Mesh. If an order is successfully added, Mesh will share it with any peers in the network and start watching it for changes (e.g. filled, canceled, expired). The returned promise will only be rejected if there was an error validating or adding the order; it will not be rejected for any invalid orders (check results.rejected instead).

Parameters:

Name	Type	Default	Description
orders	SignedOrder[]	-	An array of orders to add.
pinned	boolean	true	Whether or not the orders should be pinned. Pinned orders will not be affected by any DDoS prevention or incentive mechanisms and will always stay in storage until they are no longer fillable.

Returns: Promise‹ValidationResults›

Validation results for the given orders, indicating which orders were accepted and which were rejected.

onError

▸ onError(handler: function): void

Defined in index.ts:585

Registers a handler which will be called in the event of a critical error. Note that the handler will not be called for non-critical errors. In order to ensure no errors are missed, this should be called before startAsync.

Parameters:

▪ handler: function

The handler to be called.

▸ (err: Error): void

Parameters:

Name	Type
err	Error

Returns: void

onOrderEvents

▸ onOrderEvents(handler: function): void

Defined in index.ts:600

Registers a handler which will be called for any incoming order events. Order events are fired whenver an order is added, canceled, expired, or filled. In order to ensure no events are missed, this should be called before startAsync.

Parameters:

▪ handler: function

The handler to be called.

▸ (events: OrderEvent[]): void

Parameters:

Name	Type
events	OrderEvent[]

Returns: void

startAsync

▸ startAsync(): Promise‹void›

Defined in index.ts:611

Starts the Mesh node in the background. Mesh will automatically find peers in the network and begin receiving orders from them.

Returns: Promise‹void›
