public class DataStorePropertiesContainerBuilder
extends Object
implements org.opendaylight.yangtools.concepts.Builder<DataStorePropertiesContainer>
    Class that builds DataStorePropertiesContainer 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: 

       
     DataStorePropertiesContainer createDataStorePropertiesContainer(int fooXyzzy, int barBaz) {
         return new DataStorePropertiesContainerBuilder()
             .setFoo(new FooBuilder().setXyzzy(fooXyzzy).build())
             .setBar(new BarBuilder().setBaz(barBaz).build())
             .build();
     }

    This pattern is supported by the immutable nature of DataStorePropertiesContainer, 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
