All Implemented Interfaces:

GoogleClientRequestInitializer

public class DataflowRequestInitializer
extends CommonGoogleJsonClientRequestInitializer

Dataflow request initializer for setting properties like key and userIp.

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.
