So finally I got time to complete the blog \ud83d\ude42<\/p>\n
I’ll discuss about how we can solve the problem using templating design pattern. So what we have done, we have written a Template class “CacheTemplate” having a method getCachedData.
\ngetCachedData takes 2 parameters
\nkey: Key for which we have data cached
\ncacheCallback: If we don’t have data cached then we will call this cacheCallback to get the data and store it into cache.<\/p>\n
<\/a><\/p>\n Now taking forward the example taken in previos blog, let us apply this template to the “getPersons” method<\/p>\n Now if you compare the current implementation with the previous implementation and check the concerns we had they all are resolved.
