buffer测试用例
buffer的重载方法太多，这里不一一举例
测试代码
@Test
public void buffer3() {
System.out.println("######buffer3#####");
Flowable.just(10, 22, 13, 74, 52)
.buffer(2)//三个元素打包成一个元素
.subscribe(new Consumer<List<Integer>>() {
@Override
public void accept(List<Integer> integers) throws Exception {
System.out.println(integers.toString());
}
});
}
测试结果：
######buffer3#####
[10, 22]
[13, 74]
[52]
buffer测试用例分析
buffer操作符是把多个元素按照指定数量打包成一个元素一次过发送数据，上面测试用例实际每次把2个元素组合成一个List发送，不足2的有多少算多少.
至于其他重载方法，都是类似的作用，只是相应的配置不同。
