+/**
+ * This interface represents a textual selection. A text selection is a range of
+ * characters. Although a text selection is a snapshot taken at a particular
+ * point in time, it must not copy the line information and the selected text
+ * from the selection provider.
+ * <p>
+ * If, for example, the selection provider is a text viewer (
+ * {@link dwtx.jface.text.ITextViewer}), and a text selection is created
+ * for the range [5, 10], the line formation for the 5th character must not be
+ * determined and remembered at the point of creation. It can rather be
+ * determined at the point, when <code>getStartLine</code> is called. If the
+ * source viewer range [0, 15] has been changed in the meantime between the
+ * creation of the text selection object and the invocation of
+ * <code>getStartLine</code>, the returned line number may differ from the
+ * line number of the 5th character at the point of creation of the text
+ * selection object.
+ * <p>
+ * The contract of this interface is that weak in order to allow for efficient
+ * implementations.</p>
+ * <p>
+ * Clients may implement this interface or use the default implementation
+ * provided by {@link dwtx.jface.text.TextSelection}.</p>
