+/**
+ * Defines the target for finding and replacing strings.
+ * <p>
+ * The two main methods are <code>findAndSelect</code> and
+ * <code>replaceSelection</code>. The target does not provide any way to
+ * modify the content other than replacing the selection.
+ * <p>
+ *
+ * In order to provide backward compatibility for clients of
+ * <code>IFindReplaceTarget</code>, extension interfaces are used as a means
+ * of evolution. The following extension interfaces exist:
+ * <ul>
+ * <li>{@link dwtx.jface.text.IFindReplaceTargetExtension} since version
+ *     2.0 introducing the notion of find/replace session and of a find/replace
+ *     scope. In additions, in allows clients to replace all occurrences of a given
+ *     find query.</li>
+ * <li>{@link dwtx.jface.text.IFindReplaceTargetExtension3} since
+ *     version 3.0 allowing clients to specify search queries as regular
+ *     expressions.</li>
+ * </ul>
+ * <p>
+ * Clients of a <code>IFindReplaceTarget</code> that also implements the
+ * <code>IFindReplaceTargetExtension</code> have to indicate the start of a find/replace
+ * session before using the target and to indicate the end of the session when the
+ * target is no longer used.
