java iobject 缓冲区分析异常
91EXP 2017年04月12日

我的代码:

                // 设置缓冲区分析参数
				BufferAnalystParameter bufferAnalystParam = new BufferAnalystParameter();
				bufferAnalystParam.setEndType(BufferEndType.FLAT);
				bufferAnalystParam.setLeftDistance(20);
				bufferAnalystParam.setRightDistance(20);
				
				GeoRegion region = null;
				Map<String, Object> value = new HashMap<String, Object>();
				value.put("RNO", dv.getName());
				while (!rs.isEOF()) {
					
					Geometry geom = rs.getGeometry();
					if (geom instanceof GeoRegion) {
						region = BufferAnalystGeometry.createBuffer(geom, bufferAnalystParam);

					} else if (geom instanceof GeoText) {
						GeoText text = (GeoText) geom;
						value.put("Name", text.getText());
					}
					geom.toString();
					rs.moveNext();
				}
				rsGridReg.addNew(region, value);

我的异常信息:

请问是什么问题?怎么解决?谢谢。

1个回答

1.调试下看看geom对象的是否有值,以及类型,数据坐标单位是度还是米?

2.如果是面生成缓冲区的话,只能是圆头类型的端点。

谢谢,就是圆头类型的问题,这个异常信息不多啊。
