    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.
