class: Cache

[16:7] extends: object

A GCache allows sharing of complex data structures, in order to save system resources. GCache uses keys and values. A GCache key describes the properties of a particular resource. A GCache value is the actual resource. GCache has been marked as deprecated, since this API is rarely used and not very actively maintained.
