 /**
  * Builder for predicates.
- * <p/>
- * The builder enforces a domain specific language according to the following
- * grammar :
- * <p/>
- * <predicate> ::= <property_name> <relational_operator> <value>
- * <predicate> ::= NOT <predicate>
- * <predicate> ::= ( <predicate> )
- * <predicate> ::= <predicate> AND <predicate>
- * <predicate> ::= <predicate> OR <predicate>
- *
- * <relational_operator> ::= =|>|<|>=|<=
- * <p/>
- * The predicate builder uses the normal method chaining of the builder pattern
- * along with intermediate objects.  The use of intermediate objects allows
- * for compiler checked constraints.
- * <p/>
- * For example, the predicate builder can be used to build a predicate where
- * property1=="foo" && property2=="bar".
- *
- * <pre>
- * {@code
- * PredicateBuilder builder = new PredicateBuilder();
- *
- * Predicate predicate = builder.property(property1).equals("foo").
- *     and().property(property2).equals("bar").toPredicate();
- * }
- * </pre>
- *
- * In this example, we are starting with an instance of {@link PredicateBuilder}.
- * Calling the method {@link PredicateBuilder#property(String)} returns an
- * instance of {@link PredicateBuilderProperty} which exposes methods for attaching
- * a relational operator to the property to form a simple predicate.
- * <p/>
- * Notice that the method {@link PredicateBuilderProperty#equals(Comparable)}
- * returns an instance of {@link PredicateBuilderPredicate} which exposes methods
- * for using predicates with logical operators to create complex predicates.
- * <p/>
- * Calling the method {@link PredicateBuilderPredicate#and()} returns an instance
- * of {@link PredicateBuilder} which allows us to start over building the predicate
- * for property2.
- * <p/>
- * The reason for having these intermediate return objects is that they only
- * expose the methods that make sense for that point in the building process.
- * In other words, we can use the compiler to check the syntax of our DSL
- * grammar at compile time rather than having a single builder class with a
- * bunch of runtime checks.
- * <p/>
- * For example, if the user tries to make an inappropriate call to the and()
- * method ...
- *
- * <pre>
- * {@code
- *
- * Predicate predicate = builder.property(property1).and().
- *     property(property2).equals("bar").toPredicate();
- * }
- * </pre>
- *
- * ... the compiler will flag it as an error and the code will simply not compile.
