 /**
  * Abstract base class for {@link org.springframework.web.servlet.HandlerMapping HandlerMapping} implementations that
  * support mapping requests to {@link HandlerMethod}s rather than to handlers.
  * 
- * <p>Each {@link HandlerMethod} is registered with a unique key. Subclasses define the key type and how to create it
- * for a given handler method. Keys represent conditions for matching a handler method to a request. 
- *
- * <p>Subclasses must also define how to create a key for an incoming request. The resulting key is used to perform 
- * a {@link HandlerMethod} lookup possibly resulting in a direct match. However, when a map lookup is insufficient, 
- * the keys of all handler methods are iterated and subclasses are allowed to make an exhaustive check of key 
- * conditions against the request.
- * 
- * <p>Since there can be more than one matching key for a request, subclasses must define a comparator for sorting
- * the keys of matching handler methods in order to find the most specific match.
- *
- * @param <T> A unique key for the registration of mapped {@link HandlerMethod}s representing the conditions to
- * match a handler method to a request.
+ * @param <T> Represents a mapping key with conditions for mapping a request to a {@link HandlerMethod}.
