use of com.maddyhome.idea.vim.action.motion.MotionEditorAction in project ideavim by JetBrains.

the class MotionGroup method getMotionRange.

/**
   * This helper method calculates the complete range a motion will move over taking into account whether
   * the motion is FLAG_MOT_LINEWISE or FLAG_MOT_CHARACTERWISE (FLAG_MOT_INCLUSIVE or FLAG_MOT_EXCLUSIVE).
   *
   * @param editor     The editor the motion takes place in
   * @param context    The data context
   * @param count      The count applied to the motion
   * @param rawCount   The actual count entered by the user
   * @param argument   Any argument needed by the motion
   * @param incNewline True if to include newline
   * @return The motion's range
