Member Function Documentation

template<typename T, typename Key, typename Sto> void ONE::util::ResourceManagerBase< T, Key, Sto >::clear (   )  [inherited]

clears the cache All cached resources are destroyed. Note that calling this function will invalidate any pointer to a cached resource that may be held elsewhere.

template<typename T, typename Key, typename Sto> virtual Sto ONE::util::ResourceManagerBase< T, Key, Sto >::create (  const Key &   )  [protected, pure virtual, inherited]

Implemented in ONE::util::ResourceManager< T, Key, Handle< T > >.

template<typename T, typename Key, typename Sto> virtual void ONE::util::ResourceManagerBase< T, Key, Sto >::dispose (  Sto &   )  [protected, pure virtual, inherited]

Implemented in ONE::util::ResourceManager< T, Key, T * >, and ONE::util::ResourceManager< T, Key, Handle< T > >.

Image* ONE::render::ImageManager::doCreate (  const std::string &   )  [protected]

template<typename T, typename Key, typename Sto> Sto ONE::util::ResourceManagerBase< T, Key, Sto >::get (  const Key &  k  )  [inherited]

retrieves the object identified by k If k is found in the cache, the cached object is returned. Otherwise, a new object is created through the create function, cached via insert and returned. Parameters: k  the key identifying the desired object Returns: an object as specified above

template<typename T, typename Key, typename Sto> unsigned int ONE::util::ResourceManagerBase< T, Key, Sto >::getCount (   )  const [inline, inherited]

Returns: the number of cached objects

template<typename T, typename Key, typename Sto> bool ONE::util::ResourceManagerBase< T, Key, Sto >::isCached (  const Key &  k  )  const [inline, inherited]

checks if the object identified by k is cached The resource will not be loaded if k is not found. Note that this function runs in O(log n) time. Parameters: k  the desired key

template<typename T, typename Key, typename Sto> void ONE::util::ResourceManagerBase< T, Key, Sto >::remove (  const Key &  k  )  [inherited]

removes an object from the cache The removed object is destroyed. Note that this will invalidate any pointer to the resource that may be held elsewhere. If k is unknown, this function will fail silently. Parameters: k  a key

template<typename T, typename Key, typename Sto> virtual std::string ONE::util::ResourceManagerBase< T, Key, Sto >::toString (  const Key &   )  const [protected, pure virtual, inherited]

converts the given key to an identifier string The return value is stored in the resource map and must serve as a unique identifier for the key.

std::string ONE::render::ImageManager::toString (  const std::string &   )  const [protected]
