Detailed Description

template<typename value>
class luna::utils::vectorCache< value >

a pretty optimal multithreaded vector cahce headeronly class.

Note

the vectorcache does not check for duplicate value's

Constructor & Destructor Documentation

vectorCache() [1/2]

template<typename value >

luna::utils::vectorCache< value >::vectorCache ( )

inline

creates vectorCache with default cache size is of 200

vectorCache() [2/2]

template<typename value >

luna::utils::vectorCache< value >::vectorCache ( size_t  maxCacheSize )

inline

creates vectorcache with defined size (recommended to have size less then 1000 objects.

Parameters

maxCacheSize

~vectorCache()

template<typename value >

luna::utils::vectorCache< value >::~vectorCache ( )

inline

destroys/deletes the cache :).

Member Function Documentation

eraseValue()

template<typename value >

std::pair< cacheResult, value > luna::utils::vectorCache< value >::eraseValue ( cacheObject  key )

inline

erases value of the given key.

Parameters

cacheObject	key
value	_value

Returns

cacheOpSucces when value whas succesfully erased

cacheOpFailed when value could not be found or some other operation failed

getValue()

template<typename value >

std::pair< cacheResult, value > luna::utils::vectorCache< value >::getValue ( cacheObject  key )

inline

gets a stored cahe value using the key handle.

Parameters

key

Returns

putValue()

template<typename value >

std::pair< cacheObject, value > luna::utils::vectorCache< value >::putValue ( cacheObject *  key, value  _value  )

inline

returns a object in a vector cache using a key handle.

Parameters

key	a handle to the cahce object
_value	the cache object to store

Returns

std::pair<bool, value> when succesful returs overFlowKey and the overFLow cache value.

setValue()

template<typename value >

std::pair< cacheResult, value > luna::utils::vectorCache< value >::setValue ( cacheObject  key, value  _value  )

inline

sets the current value of the given cacheObject key.

Parameters

cacheObject	key the key to overwite
_value	the value to overwrite the current value

Returns
