 <p>Let's look at some more example PTypes created using the common primitive 
and collection types. For most of your pipelines,
 you will use one type family exclusively, and so you can cut down on some of 
the boilerplate in your classes by importing
 all of the methods from the <code>Writables</code> or <code>Avros</code> 
classes into your class:</p>

 <p>Both type families also have a method named <code>PType&lt;T&gt; 
records(Class&lt;T&gt; clazz)</code> that can be used to create PTypes that 
support the common
 record format for each type family. For the WritableTypeFamily, the records 
method supports PTypes for implementations of the <code>Writable</code>
 interface, and for the AvroTypeFamily, the records method supports PTypes for 
implementations of Avro's <code>IndexedRecord</code> interface, which
