The basic hashtable is intended to be used to support a variety of different datastructures such as map, set, multimap, multiset, linkedmap, generationcache, etc. Consequently its interface is fairly primitive. The basic hashtable supports copy-on-write style functionality using SharedBuffer. The change introduces a simple generic function in TypeHelpers for specifying hash functions. The idea is to add template specializations of hash_type<T> next to the relevant data structures such as String8, String16, sp<T>, etc. Change-Id: I2c479229e9d4527b4fbfe3b8b04776a2fd32c973
