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;
        }
