Class ConfigBuilder

  • @Generated("mdsal-binding-generator")
public class ConfigBuilder
extends Object
    Class that builds Config 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: 

       
     Config createConfig(int fooXyzzy, int barBaz) {
         return new ConfigBuilder()
             .setFoo(new FooBuilder().setXyzzy(fooXyzzy).build())
             .setBar(new BarBuilder().setBaz(barBaz).build())
             .build();
     }

    This pattern is supported by the immutable nature of Config, 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

        Set fields from given grouping argument. Valid argument is instance of one of following types:
        Parameters:
        arg - grouping object
        Throws:
        IllegalArgumentException - if given argument is none of valid types or has property with incompatible value

      • augmentation

        public <E$$ extends org.opendaylight.yangtools.yang.binding.Augmentation<Config>> E$$ 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 ConfigBuilder addAugmentation​(org.opendaylight.yangtools.yang.binding.Augmentation<Config> augmentation)

        augmentation - augmentation to be added
        Returns:
        this builder
        Throws:
        NullPointerException - if augmentation is null

      • removeAugmentation

        public ConfigBuilder removeAugmentation​(Class<? extends org.opendaylight.yangtools.yang.binding.Augmentation<Config>> 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
