public class DataflowRequestInitializer
extends com.google.api.client.googleapis.services.json.CommonGoogleJsonClientRequestInitializer
The simplest usage is to use it to set the key parameter:
public static final GoogleClientRequestInitializer KEY_INITIALIZER = new DataflowRequestInitializer(KEY);
There is also a constructor to set both the key and userIp parameters:
public static final GoogleClientRequestInitializer INITIALIZER = new DataflowRequestInitializer(KEY, USER_IP);
If you want to implement custom logic, extend it like this:
public static class MyRequestInitializer extends DataflowRequestInitializer { @Override public void initializeDataflowRequest(DataflowRequest<?> request) throws IOException { // custom logic } }
Finally, to set the key and userIp parameters and insert custom logic, extend it like this:
public static class MyRequestInitializer2 extends DataflowRequestInitializer { public MyKeyRequestInitializer() { super(KEY, USER_IP); } @Override public void initializeDataflowRequest(DataflowRequest<?> request) throws IOException { // custom logic } }
Subclasses should be thread-safe.
