Interface Gateway

Gateway represents the connection of a specific client identity to a Fabric Gateway. A Gateway is obtained using the connect function.

This type implements the Disposable interface, allowing instances to be disposed of with ECMAScript explicit resource management and the using keyword instead of calling close directly.

Methods

[dispose]

close

  • close(): void

  • Close the gateway when it is no longer required. This releases all resources associated with networks and contracts obtained using the Gateway, including removing event listeners.

    Returns void

getIdentity

getNetwork

  • getNetwork(channelName: string): Network

  • Get a network representing the named Fabric channel.

    Parameters

    • channelName: string

      Fabric channel name.

    Returns Network
