构造器详细资料

LayerExtensionBase

public LayerExtensionBase(long handle)

构建拓展图层

参数:

handle - 拓展图层对象的句柄

方法详细资料

OnDraw

public void OnDraw(MapPainter painter)

ToXML

public String ToXML(WorkspaceVersion version)

FromXML

public void FromXML(String xml)

getBounds

public Rectangle2D getBounds()

获取拓展图层的范围

覆盖:

getBounds 在类中 Layer

返回:

拓展图层的范围

抛出:

IllegalStateException - 当前对象已被释放

setBounds

public void setBounds(Rectangle2D bounds)

设置拓展图层的范围

参数:

bounds - 拓展图层的范围

抛出:

IllegalStateException - 当前对象已被释放

getExtensionType

public int getExtensionType()

获取拓展类型

返回:

拓展类型

抛出:

IllegalStateException - 当前对象已被释放

setExtensionType

public void setExtensionType(int type)

设置拓展类型

参数:

type - 拓展类型

抛出:

IllegalStateException - 当前对象已被释放

dispose

public void dispose()

销毁当前拓展图层对象

指定者:

dispose 在接口中 IDisposable

addLayerExtensionBaseCreatedListener

public static void addLayerExtensionBaseCreatedListener(LayerExtensionBaseCreatedListener l)

添加拓展图层创建后监听器

参数:

l - 创建后监听器

removeLayerExtensionBaseCreatedListener

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。
