+/**
+ * An entity that can be sent or received with an HTTP message.
+ * Entities can be found in some
+ * {@link HttpEntityEnclosingRequest requests} and in
+ * {@link HttpResponse responses}, where they are optional.
+ * <p>
+ * There are three distinct types of entities in HttpCore,
+ * depending on where their {@link #getContent content} originates:
+ * <ul>
+ * <li><b>streamed</b>: The content is received from a stream, or
+ *     generated on the fly. In particular, this category includes
+ *     entities being received from a {@link HttpConnection connection}.
+ *     {@link #isStreaming Streamed} entities are generally not
+ *      {@link #isRepeatable repeatable}.
+ *     </li>
+ * <li><b>self-contained</b>: The content is in memory or obtained by
+ *     means that are independent from a connection or other entity.
+ *     Self-contained entities are generally {@link #isRepeatable repeatable}.
+ *     </li>
+ * <li><b>wrapping</b>: The content is obtained from another entity.
+ *     </li>
+ * </ul>
+ * This distinction is important for connection management with incoming
+ * entities. For entities that are created by an application and only sent
+ * using the HTTP components framework, the difference between streamed
+ * and self-contained is of little importance. In that case, it is suggested
+ * to consider non-repeatable entities as streamed, and those that are
+ * repeatable (without a huge effort) as self-contained.
