Windchill二次開發-查詢篇-文檔查詢

繼續介紹在系統中如何查詢WTDocument對象

public static WTDocument getDoc(String num){
		if(num == null || num.trim().length()==0){
			return null ;
		}
		WTDocument doc = null ;
		QueryResult qr ;
		try {
			QuerySpec qs = new QuerySpec(WTDocument.class) ;
			qs.appendWhere(new SearchCondition(WTDocument.class,WTDocument.NUMBER,SearchCondition.EQUAL,num),new int[] {0}) ;
			qr = PersistenceHelper.manager.find((StatementSpec)qs);
			//過濾最新版本
			LatestConfigSpec ls = new LatestConfigSpec() ;
			QueryResult qrLs = ls.process(qr) ;
			System.out.println(qrLs.hasMoreElements()) ;
			while(qrLs.hasMoreElements()){
				doc = (WTDocument) qrLs.nextElement() ;
			}
		} catch (WTException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return doc ;
