Tuple.append介绍

[英]Append a field to a tuple. This method is not efficient as it may force copying of existing data in order to grow the data structure. Whenever possible you should construct your Tuple with TupleFactory#newTuple(int) and then fill in the values with #set(int,Object), rather than construct it with TupleFactory#newTuple() and append values.
[中]将字段附加到元组。这种方法效率不高，因为它可能会强制复制现有数据以增加数据结构。只要有可能，就应该用TupleFactory#newTuple（int）构造元组，然后用#set（int，Object）填充值，而不是用TupleFactory#newTuple（）构造元组并附加值。
