Example 1 with EndpointDescription

the class OpcUaClient method create.

/**
 * Create and configure an {@link OpcUaClient} by selecting an {@link EndpointDescription} from a list of endpoints
 * retrieved via the GetEndpoints service from the server at {@code endpointUrl} and building an
 * {@link OpcUaClientConfig} using that endpoint.

 * @param endpointUrl    the endpoint URL of the server to connect to and retrieve endpoints from.
 * @param selectEndpoint a function that selects the {@link EndpointDescription} to connect to from the list of
 *                       endpoints from the server.
 * @param buildConfig    a function that configures an {@link OpcUaClientConfigBuilder} and then builds and returns
 *                       an {@link OpcUaClientConfig}.
 * @return a configured {@link OpcUaClient}.
 * @throws UaException if the endpoints could not be retrieved or the client could not be created.
