fetch()

QVariant KoResourceCacheStorage::fetch ( const QString & key ) const

overridevirtual

fetch a cached object from the cache using key

Implements KoResourceCacheInterface.

put()

void KoResourceCacheStorage::put ( const QString & key, const QVariant & value )

overridevirtual

store a cached object value into the cache using key WARNING: storing an object twice with the same key is considered as invalid operation and will assert! This behavior is intentional to avoid cache key aliasing.

This assert here is intentional! It catches cache key aliasing problems. See dox in KoResourceCacheInterface

Implements KoResourceCacheInterface.
