Method Detail

getCacheId

String getCacheId()

String identifier which is guaranteed to include sufficient information to assure to be different for two instances which could produce different result. It is typically used as basis for calculation of hash codes (like MD5, SHA1, SHA2 etc) of (collections of) objects.

It is hoped that identical object (or objects which could result in identical results) have the save cacheId.

This is similar to Object.toString() but with additional guarantees. This is similar to Object.hashCode() but using String type.

Returns:

id which can be used for caching purposes
