Detailed Description

template<class ProxyT>
class llvm::cas::OnDiskTrieRawHashMap::PointerImpl< ProxyT >

Template class to implement a pointer type into the trie data structure.

It provides pointer-like operation, e.g., dereference to get underlying data. It also reserves the top 16 bits of the pointer value, which can be used to pack additional information if needed.
