plsql - 游标循环并继续执行: unexpected behaviour

Question

由于截止日期的压力，我可能会忽略一些东西。但是这种行为令我惊讶。
好像游标缓存了100行，而continue语句刷新了缓存
并从获取新缓存的第一条记录开始。

我将其范围缩小到以下脚本:

drop table test1;

create table test1 (test1_id NUMBER);

begin
  for i in 1..300
  loop
    insert into test1 values (i);
  end loop;
end;
/

declare
  cursor c_test1 is
  select *
  from test1;
begin
  for c in c_test1
  loop
     if mod(c.test1_id,10) = 0
     then
      dbms_output.put_line(c_test1%ROWCOUNT||' '||c.test1_id||' Continue');
      continue;
     end if;
     dbms_output.put_line(c_test1%ROWCOUNT||' '||c.test1_id||' Process');
  end loop;
end;
/
