Abstract
Methods for a treatment of cached objects are described. In one embodiment, management of a region of a cache is configured with an eviction policy plug-in and a storage plug-in. The eviction policy plug-in includes code to evict an object that is cached in the region of cache. The storage plug-in includes code to execute a function involving a key attribute manipulation function that, using a first hashing function and a key, identifies a table of attributes for the first object located within the region of cache, and using a second hashing function and an attribute name, gets a specific attribute for the first object from the table, the key being registered with the storage plug-in.
