Method Detail

clear

public any clear(any objectKey)

Clears an object from the cache by using its cache key. Returns false if object was not removed or did not exist anymore

Parameters:: objectKey - The object cache key

clearAll

public void clearAll()

Clear all the cache elements from the cache

clearQuiet

public any clearQuiet(any objectKey)

Clears an object from the cache by using its cache key. Returns false if object was not removed or did not exist anymore without doing statistics or updating listeners

Parameters:: objectKey - The object cache key

clearStatistics

public void clearStatistics()

Clear the cache statistics

configure

public void configure()

This method makes the cache ready to accept elements and run. Usualy a cache is first created (init), then wired and then the factory calls configure() on it

expireAll

public void expireAll()

Expire all the elments in the cache (if supported by the provider)

expireObject

public void expireObject(any objectKey)

Expires an object from the cache by using its cache key. Returns false if object was not removed or did not exist anymore (if supported by the provider)

Parameters:: objectKey - The object cache key

get

public any get(any objectKey)

Get an object from the cache and updates stats

Parameters:: objectKey - The object key

getCachedObjectMetadata

public any getCachedObjectMetadata(any objectKey)

Get a cache objects metadata about its performance. This value is a structure of name-value pairs of metadata.

Parameters:: objectKey - The key of the object to lookup its metadata

getCacheFactory

public any<CacheFactory> getCacheFactory()

Get the cache factory reference this cache provider belongs to

getConfiguration

public any getConfiguration()

Get the structure of configuration parameters for the cache

getEventManager

public any getEventManager()

Get this cache managers event listener manager

getKeys

public any getKeys()

Returns a list of all elements in the cache, whether or not they are expired.

getName

public any getName()

Get the name of this cache

getObjectStore

public any<IObjectStore> getObjectStore()

If the cache provider implements it, this returns the cache's object store as type: cachebox.system.cache.store.IObjectStore

getQuiet

public any getQuiet(any objectKey)

Get an object from the cache without updating stats or listners

Parameters:: objectKey - The object key

getSize

public any getSize()

Get the number of elements in the cache

getStats

public any<ICacheStats> getStats()

Get the cache statistics object as cachebox.system.cache.util.ICacheStats

getStoreMetadataKeyMap

public any getStoreMetadataKeyMap()

Get a key lookup structure where cachebox can build the report on. Ex: [timeout=timeout,lastAccessTimeout=idleTimeout]. It is a way for the visualizer to construct the columns correctly on the reports

getStoreMetadataReport

public any getStoreMetadataReport()

Get a structure of all the keys in the cache with their appropriate metadata structures. This is used to build the reporting.[keyX->[metadataStructure]]

isEnabled
