注释写的这么清楚了,还用解释啥?
// A type, typically a collection, that satisfies sort.Interface can be
// sorted by the routines in this package. The methods require that the
// elements of the collection be enumerated by an integer index.
type Interface interface {
// Len is the number of elements in the collection.
Len() int
// Less reports whether the element with
// index i should sort before the element with index j.
Less(i, j int) bool
// Swap swaps the elements with indexes i and j.
Swap(i, j int)
}
本文详细介绍了排序接口的实现原理,包括长度、比较和交换三个核心方法。通过整数索引枚举集合元素,实现了集合的排序功能。此接口为集合提供了通用的排序能力,适用于多种数据类型。
