@Generated("mdsal-binding-generator") public class SessionBuilder extends Object
Class that buildsSession
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:
Session createSession(int fooXyzzy, int barBaz) { return new SessionBuilder() .setFoo(new FooBuilder().setXyzzy(fooXyzzy).build()) .setBar(new BarBuilder().setBaz(barBaz).build()) .build(); }
This pattern is supported by the immutable nature of Session, 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

getOpen
public Open getOpen()
Return current value associated with the property corresponding toOpenObject.getOpen()
.- Returns:
- current value
-
augmentation
public <E$$ extends org.opendaylight.yangtools.yang.binding.Augmentation<Session>> E$$ 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
- ifaugmentType
isnull

setOpen
public SessionBuilder setOpen(Open value)
Set the property corresponding toOpenObject.getOpen()
to the specified value.- Parameters:
value
- desired value- Returns:
