Example 1 with SoftWrapModel

use of com.intellij.openapi.editor.SoftWrapModel in project intellij-community by JetBrains.

the class SoftWrapHelper method isCaretAfterSoftWrap.

/**
   * Every soft wrap implies that multiple visual positions correspond to the same document offset. We can classify
   * such positions by the following criteria:
   * <pre>
   * <ul>
   *   <li>positions from visual line with soft wrap start;</li>
   *   <li>positions from visual line with soft wrap end;</li>
   * </ul>
   * </pre>
   * <p/>
   * This method allows to answer if caret offset of the given editor points to soft wrap and visual caret position
   * belongs to the visual line where soft wrap end is located.
   *
   * @return          <code>true</code> if caret offset of the given editor points to visual position that belongs to
   *                  visual line where soft wrap end is located
