> 3. THE C++ API
> This section discusses the most important aspects of Pre-
> gel's C++ API, omitting relatively mechanical issues.
> Writing a Pregel program involves subclassing the prede-
> ned Vertex class (see Figure 3). Its template arguments
> dene three value types, associated with vertices, edges,
> and messages. Each vertex has an associated value of the
> specied type. This uniformity may seem restrictive, but
> users can manage it by using 
> exible types like protocol
> buers [42].

> We need to add two template arguments for value types of vertex and edge to the Vertex
abstract class.
