Detailed Description

template<typename KeyType>
class Scine::Molassembler::Temple::Cache< KeyType >

A class that can store completely variant types in a type safe manner using boost::any. Only the key type is fixed. Selective invalidation of cached data is possible, and cache elements can also be set as generatable, i.e. a function that generates the cache data can be passed. On first use, the cache element is then generated.

template<typename T >

T Scine::Molassembler::Temple::Cache< KeyType >::getGeneratable ( const KeyType &  key )

inline

Fetches the value of a generatable cache item. Handles all corner cases of whether the cache element is present or not.
