Enum Constant Summary

Enum Constants

Enum Constant and Description
CACHE_REMOTE 先使用缓存，不管是否存在，仍然请求网络，会回调两次
CACHE_REMOTE_DISTINCT 先使用缓存，不管是否存在，仍然请求网络，会先把缓存回调给你， 等网络请求回来发现数据是一样的就不会再返回，否则再返回 （这样做的目的是防止数据是一样的你也需要刷新界面）
DEFAULT 完全按照HTTP协议的默认缓存规则，走OKhttp的Cache缓存
FIRST_CACHE 先加载缓存，缓存没有再去请求网络
FIRST_REMOTE 先请求网络，请求网络失败后再加载缓存
NO_CACHE 不使用缓存,该模式下,mCacheKey,cacheMaxAge 参数均无效
ONLY_CACHE 只读取缓存
ONLY_REMOTE 仅加载网络，但数据依然会被缓存

Method Detail

values

public static CacheMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CacheMode c : CacheMode.values())

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name
