Query.findVisit介绍

[英]Execute the query using callbacks to a visitor to process the resulting beans one at a time.

Similar to findIterate() this query method does not require all the result beans to be all held in memory at once and as such is useful for processing large queries.

Query<Customer> query = server.find(Customer.class) 
.fetch("contacts", new FetchConfig().query(2)) 
.where().gt("id", 0) 
.orderBy("id") 
.setMaxRows(2); 
query.findVisit(new QueryResultVisitor<Customer>() { 
public boolean accept(Customer customer) { 
// do something with customer 
System.out.println("-- visit " + customer); 
return true; 
} 
});

[中]使用对访问者的回调执行查询,一次一个地处理生成的bean。
与findIterate()类似,此查询方法不要求所有结果bean同时保存在内存中,因此对于处理大型查询非常有用。

Query<Customer> query = server.find(Customer.class) 
.fetch("contacts", new FetchConfig().query(2)) 
.where().gt("id", 0) 
.orderBy("id") 
.setMaxRows(2); 
query.findVisit(new QueryResultVisitor<Customer>() { 
public boolean accept(Customer customer) { 
// do something with customer 
System.out.println("-- visit " + customer); 
return true; 
} 
});
