Class AggregationBuilder
java.lang.Object
org.opendaylight.yang.gen.v1.http.openconfig.net.yang.interfaces.aggregate.rev200501.aggregation.logical.top.AggregationBuilder
Class that builds
Aggregation 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:
Aggregation createAggregation(int fooXyzzy, int barBaz) {
return new AggregationBuilder()
.setFoo(new FooBuilder().setXyzzy(fooXyzzy).build())
.setBar(new BarBuilder().setBaz(barBaz).build())
.build();
}
This pattern is supported by the immutable nature of Aggregation, 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$$ extends org.opendaylight.yangtools.yang.binding.Augmentation<Aggregation>> E$$ 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
nullif not present - Throws:
NullPointerException- ifaugmentTypeisnull
-
setConfig
Set the property corresponding toAggregation.getConfig()to the specified value.- Parameters:
value- desired value- Returns:
- this builder
