Summary

Constructor

let point1 = new hmap.geom.Point(new hmap.basetype.Coordinate(120,30,0));
let point2 = new hmap.geom.Point(new hmap.basetype.Coordinate(121,30,0));
let lineArrowGeom = new hmap.geomext.PolylineArrow([point1,point2]);

Methods

getBBox() → {module:basetype~BBox}

获取拓展几何的三维包围盒

Returns:

module:basetype~BBox -

返回三维包围盒

getCoordSeqs() → {Array.<module:basetype~CoordSeq>}

获取折线箭头的坐标序列数组

Returns:

Array.<module:basetype~CoordSeq> -

坐标序列数组

Example

let coordSeqs = lineArrowGeom.getCoordSeqs();

getCtrlPoints() → {Array.<module:geom~Point>}

获取控制点的几何数组

Returns:

Array.<module:geom~Point> -

点几何数组

Example

let points = geomext.getCtrlPoints();

getLines() → {Array.<module:geom~Line>}

获取折线箭头中所有的线状几何体对象

Returns:

Array.<module:geom~Line> -

线状几何体的数组

Example

let lines = lineArrowGeom.getLines();

getType() → {String}

获取几何体类型

Returns:

String -

hmap拓展的几何类型，参见GeometryExtType

Example

let type = lineArrowGeom.getType();

setCtrlPoints(points)

重新设置折线箭头的控制点。

Parameters:

Name	Type	Description
points	Array.<module:geom~Point>	点几何体数组，数组长度小于2或非数组类型时，则抛出构造异常。

Throws:

RangeError | TypeError -

数组长度小于2或非数组类型，则抛出构造异常。

Example

let point1 = new hmap.geom.Point(new hmap.basetype.Coordinate(121,30,0));
 let point2 = new hmap.geom.Point(new hmap.basetype.Coordinate(122,30,0));
 lineArrowGeom.setCtrlPoints([point1,point2]);

toMultiLine() → {module:geom~MultiLine}

将折线箭头转为多线要素

Returns:

module:geom~MultiLine -

多线几何

Example

let multiLine = lineArrowGeom.toMultiLine();
