```
public static void removeLayerExtensionBaseCreatedListener(LayerExtensionBaseCreatedListener l)
```
    移除拓展图层创建后监听器
    
    参数:
    
    l - 创建后监听器
  - hitTest
```
public boolean hitTest(Point2D pt,
                       double tolerance,
                       String resultExpression,
                       ArrayList<GeoText> testResult)
```
    从类复制的说明: Layer
    
    返回选中的专题元素。若指定的点与专题元素上最近点的距离是在指定的容限范围，则该专题元素被选中。目前只支持标签专题图，
    
    覆盖:
    
    hitTest 在类中 Layer
    
    参数:
    
    pt - 要测试的点。
    
    tolerance - 指定的容限。
    
    resultExpression - 指定的字段表达式，设置该字段表达式之后可以，可以从结果中取到特定的专题元素对应的几何对象的相关数据。
    
    testResult - 用于存储该方法得到的专题图元素，在没有得到满足条件的对象时，该参数对象的长度为 0，该参数不能为 null。
    
    返回:
    
    返回是否得到了专题图元素，true 表示通过该方法得到了专题元素。
