DATAMONGO-1527 - Release version 2.0 M1 (Kay).

Adopt type hint assertion for existing _class field checks. Simplify test code to use Collections.singletonList instead of Arrays.asList. Replace BasicDBList with List in JavaDoc. Use type inference for DocumentTestUtils.getAsDBList to avoid casts in test code. Extend documentation.

+The primary goal of the [Spring Data](http://projects.spring.io/spring-data) project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.
 
-At this point your best bet is to look at the Look at the [JavaDocs](http://static.springsource.org/spring-data/data-document/docs/1.0.0.BUILD-SNAPSHOT/spring-data-mongodb/apidocs/) for MongoDB integration and corresponding and source code. For more detailed questions, use the [forum](http://forum.springsource.org/forumdisplay.php?f=80). If you are new to Spring as well as to Spring Data, look for information about [Spring projects](http://www.springsource.org/projects). 
+The Spring Data MongoDB project aims to provide a familiar and consistent Spring-based programming model for new datastores while retaining store-specific features and capabilities. The Spring Data MongoDB project provides integration with the MongoDB document database. Key functional areas of Spring Data MongoDB are a POJO centric model for interacting with a MongoDB DBCollection and easily writing a repository style data access layer.
 
-The [User Guide](http://static.springsource.org/spring-data/data-document/docs/1.0.0.BUILD-SNAPSHOT/reference/html/) (A work in progress).

+MongoTemplate is the central support class for Mongo database operations. It provides:
 
 * Basic POJO mapping support to and from BSON
-* Connection Affinity callback
-* Exception translation into Spring's [technology agnostic DAO exception hierarchy](http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/dao.html#dao-exceptions).
+* Convenience methods to interact with the store (insert object, update objects) and MongoDB specific ones (geo-spatial operations, upserts, map-reduce etc.)
+* Connection affinity callback
+* Exception translation into Spring's [technology agnostic DAO exception hierarchy](http://docs.spring.io/spring/docs/current/spring-framework-reference/html/dao.html#dao-exceptions).
 
-Future plans are to support optional logging and/or exception throwing based on WriteResult return value, common map-reduce operations, GridFS operations.  A simple API for partial document updates is also planned.
+### Spring Data repositories
 
-### Easy Data Repository generation
+To simplify the creation of data repositories Spring Data MongoDB provides a generic repository programming model. It will automatically create a repository proxy for you that adds implementations of finder methods you specify on an interface.  
 
-To simplify the creation of Data Repositories a generic Repository interface and default implementation is provided.  Furthermore, Spring will automatically create a Repository implementation for you that adds implementations of finder methods you specify on an interface.  
+For example, given a `Person` class with first and last name properties, a `PersonRepository` interface that can query for `Person` by last name and when the first name matches a like expression is shown below:
 
-The Repository interface is
+```java
+public interface PersonRepository extends CrudRepository<Person, Long> {
 
-        public interface Repository<T, ID extends Serializable> { 
+  List<Person> findByLastname(String lastname);
 
-          T save(T entity);
+  List<Person> findByFirstnameLike(String firstname);
+}
+```
 
-          List<T> save(Iterable<? extends T> entities);
+The queries issued on execution will be derived from the method name. Extending `CrudRepository` causes CRUD methods being pulled into the interface so that you can easily save and find single entities and collections of them.
 
-          T findById(ID id);
+You can have Spring automatically create a proxy for the interface by using the following JavaConfig:
 
-          boolean exists(ID id);
+```java
+@Configuration
+@EnableMongoRepositories
+class ApplicationConfig extends AbstractMongoConfiguration {
 
-          List<T> findAll();
+  @Override
+  public Mongo mongo() throws Exception {
+    return new MongoClient();
+  }
 
-          Long count();
+  @Override
+  protected String getDatabaseName() {
+    return "springdata";
+  }
+}
+```
 
-          void delete(T entity);
+This sets up a connection to a local MongoDB instance and enables the detection of Spring Data repositories (through `@EnableMongoRepositories`). The same configuration would look like this in XML:
 
-          void delete(Iterable<? extends T> entities);
+```xml
+<bean id="template" class="org.springframework.data.mongodb.core.MongoTemplate">
+  <constructor-arg>
+    <bean class="com.mongodb.MongoClient">
+       <constructor-arg value="localhost" />
+       <constructor-arg value="27017" />
+    </bean>
+  </constructor-arg>
+  <constructor-arg value="database" />
+</bean>
 
-          void deleteAll();
-        }
+<mongo:repositories base-package="com.acme.repository" />
+```
 
+This will find the repository interface and register a proxy object in the container. You can use it as shown below:
 
-The MongoRepository extends Repository and will in future add more Mongo specific methods.
+```java
+@Service
+public class MyService {
 
-    public interface MongoRepository<T, ID extends Serializable> extends
-        Repository<T, ID> {
-    }
+  private final PersonRepository repository;
 
-SimpleMongoRepository is the out of the box implementation of the MongoRepository you can use for basid CRUD operations.  
+  @Autowired
+  public MyService(PersonRepository repository) {
+    this.repository = repository;
+  }
 
-To go beyond basic CRUD, extend the MongoRepository interface and supply your own finder methods that follow simple naming conventions such that they can be easily converted into queries.  
+  public void doWork() {
 
-For example, given a Person class with first and last name properties, a PersonRepository interface that can query for Person by last name and when the first name matches a regular expression is shown below
+     repository.deleteAll();
 
-    public interface PersonRepository extends MongoRepository<Person, Long> {
+     Person person = new Person();
+     person.setFirstname("Oliver");
+     person.setLastname("Gierke");
+     person = repository.save(person);
 
-      List<Person> findByLastname(String lastname);
+     List<Person> lastNameResults = repository.findByLastname("Gierke");
+     List<Person> firstNameResults = repository.findByFirstnameLike("Oli*");
+ }
+}
+```
 
-      List<Person> findByFirstnameLike(String firstname);
-    }
-
-You can have Spring automatically generate the implemention as shown below
-
-        <bean id="template" class="org.springframework.data.document.mongodb.MongoTemplate">
-                <constructor-arg>
-                        <bean class="com.mongodb.Mongo">
-                                <constructor-arg value="localhost" />
-                                <constructor-arg value="27017" />
-                        </bean>
-                </constructor-arg>
-                <constructor-arg value="database" />
-                <property name="defaultCollectionName" value="springdata" />
-        </bean>
-
-        <bean class="org.springframework.data.document.mongodb.repository.MongoRepositoryFactoryBean">
-                <property name="template" ref="template" />
-                <property name="repositoryInterface" value="org.springframework.data.document.mongodb.repository.PersonRepository" />
-        </bean>
-
-This will register an object in the container named PersonRepository.  You can use it as shown below
-
-     @Service
-     public class MyService {
-
-        @Autowired
-        PersonRepository repository;
-
-
-        public void doWork() {
-
-           repository.deleteAll();
-
-           Person person = new Person();
-           person.setFirstname("Oliver");
-           person.setLastname("Gierke");
-           person = repository.save(person);
-
-           List<Person> lastNameResults = repository.findByLastname("Gierke");
-
-           List<Person> firstNameResults = repository.findByFirstnameLike("Oli*");
-
-       }
-    }
