Detailed Description

template<typename Key, typename Hash>
class fdl::detail::TlStringCache< Key, Hash >

Bounded thread-local string cache with auto-eviction.

When the number of cached entries reaches fdl::constants::kTlCacheMaxEntries, the cache is cleared entirely before the new entry is inserted.

Template Parameters

Key	Cache key type (must be hashable and equality-comparable).
Hash	Hash functor for Key.

get()

template<typename Key , typename Hash >

std::string & fdl::detail::TlStringCache< Key, Hash >::get ( const Key &  key )

inline

If the cache exceeds the size limit, it is cleared first. The returned reference is valid until the next call to get() that triggers eviction.

Parameters

key	The cache key to look up.

Returns

Reference to the cached string (may be empty if newly created).
