Class LoopbackActionBuilder

java.lang.Object
org.opendaylight.yang.gen.v1.urn.opendaylight.action.types.rev131112.action.action.loopback.action._case.LoopbackActionBuilder
@Generated("mdsal-binding-generator") public class LoopbackActionBuilder extends Object
Class that builds LoopbackAction instances. Overall design of the class is that of a fluent interface, where method chaining is used.

In general, this class is supposed to be used like this template: 

   
     LoopbackAction createLoopbackAction(int fooXyzzy, int barBaz) {
         return new LoopbackActionBuilder()
             .setFoo(new FooBuilder().setXyzzy(fooXyzzy).build())
             .setBar(new BarBuilder().setBaz(barBaz).build())
             .build();
     }

This pattern is supported by the immutable nature of LoopbackAction, as instances can be freely passed around without worrying about synchronization issues.

As a side note: method chaining results in:

  • very efficient Java bytecode, as the method invocation result, in this case the Builder reference, is on the stack, so further method invocations just need to fill method arguments for the next method invocation, which is terminated by build(), which is then returned from the method
  • better understanding by humans, as the scope of mutable state (the builder) is kept to a minimum and is very localized
  • better optimization opportunities, as the object scope is minimized in terms of invocation (rather than method) stack, making escape analysis a lot easier. Given enough compiler (JIT/AOT) prowess, the cost of th builder object can be completely eliminated

    • augmentation

      public <E$$ extends org.opendaylight.yangtools.yang.binding.Augmentation<LoopbackAction>> E$$ augmentation(Class<E$$> augmentationType)
      Return the specified augmentation, if it is present in this builder.
      Type Parameters:
      E$$ - augmentation type
      Parameters:
      augmentationType - augmentation type class
      Returns:
      Augmentation object from this builder, or null if not present
      Throws:
      NullPointerException - if augmentType is null

    • addAugmentation

      public LoopbackActionBuilder addAugmentation(org.opendaylight.yangtools.yang.binding.Augmentation<LoopbackAction> augmentation)
      Add an augmentation to this builder's product.
      Parameters:
      augmentation - augmentation to be added
      Returns:
      this builder
      Throws:
      NullPointerException - if augmentation is null

    • removeAugmentation

      public LoopbackActionBuilder removeAugmentation(Class<? extends org.opendaylight.yangtools.yang.binding.Augmentation<LoopbackAction>> augmentationType)
      Remove an augmentation from this builder's product. If this builder does not track such an augmentation type, this method does nothing.
      Parameters:
      augmentationType - augmentation type to be removed
      Returns:
      this builder

    • build

      public @NonNull LoopbackAction build()
      A new LoopbackAction instance.
      Returns:
      A new LoopbackAction instance.
