- * Calculate slider move result.
- * Usage:
- * (1) If both handle0 and handle1 are needed to be moved, set minSpan the same as
- * maxSpan and the same as `Math.abs(handleEnd[1] - handleEnds[0])`.
- * (2) If handle0 is forbidden to cross handle1, set minSpan as `0`.
- *
- * @param delta Move length.
- * @param handleEnds handleEnds[0] can be bigger then handleEnds[1].
- * handleEnds will be modified in this method.
- * @param extent handleEnds is restricted by extent.
- * extent[0] should less or equals than extent[1].
- * @param handleIndex Can be 'all', means that both move the two handleEnds.
- * @param minSpan The range of dataZoom can not be smaller than that.
- * If not set, handle0 and cross handle1. If set as a non-negative
- * number (including `0`), handles will push each other when reaching
- * the minSpan.
- * @param maxSpan The range of dataZoom can not be larger than that.
- * @return The input handleEnds.
