本文介绍了一种在ArcGIS中将元素插入特定图层的方法。提供了三种不同的实现方式：单个元素插入、单个元素插入第二种方式及批量元素插入。通过创建特征缓冲区或直接创建特征对象，并设置形状属性来完成插入操作。

主要是用于提取元素插入到图层中：

 private IFeatureClass insertFeature_one( IFeatureClass fclass, IFeature feature){
         try {
        	IFeatureBuffer pFeatBuf = fclass.createFeatureBuffer();
        	IFeature pFeat = (IFeature) pFeatBuf;
        			 pFeat.setShapeByRef(feature.getShape());	
			IFeatureCursor pFeatCur = fclass.IFeatureClass_insert(true);
			pFeatCur.insertFeature(pFeatBuf);
			pFeatCur.flush();
		} catch (AutomationException e) {
			e.printStackTrace();
		} catch (IOException e){
			e.printStackTrace();
		}
		return fclass;	
    }
    
    private IFeatureClass insertFeature_second(IFeatureClass fclass, IFeature feature){
        try {
	       	 IFeature pFeature = fclass.createFeature();
	       	 pFeature.setShapeByRef(feature.getShape());
	       	 pFeature.store();
		} catch (AutomationException e) {
			e.printStackTrace();
		} catch (IOException e){
			e.printStackTrace();
		}
		return fclass;
    }
    
    private IFeatureClass insertFeatures( IFeatureClass fclass, List<IFeature> features){
        try {
        	IFeatureBuffer pFeatBuf = null;
        	IFeatureCursor pFeatCur = null;
        	for(int i=0; i<features.size(); i++){
        		pFeatBuf = fclass.createFeatureBuffer();
        		pFeatCur = fclass.IFeatureClass_insert(true);
            	IFeature pFeat = (IFeature) pFeatBuf;
            			 pFeat.setShapeByRef(features.get(i).getShape());	
    			pFeatCur.insertFeature(pFeatBuf);
    			if(i/100 == 0){
    				pFeatCur.flush();
    			}
        	}
        	pFeatCur.flush();
		} catch (AutomationException e) {
			e.printStackTrace();
		} catch (IOException e){
			e.printStackTrace();
		}
		return fclass;
    }
