+    @class wxWrapperInputStream
+
+    A wrapper input stream is a kind of filter stream which forwards all the
+    operations to its base stream. This is useful to build utility classes such
+    as wxFSInputStream.
+
+    @note
+    The interface of this class is the same as that of wxInputStream.
+    Only a constructor differs and it is documented below.
+
+    @library{wxbase}
+    @category{streams}
+
+    @see wxFSInputStream, wxFilterInputStream
+    @since 2.9.4
