Methods

Modifier and Type	Method and Description
java.lang.Object	getCacheElement(java.lang.Object pKey) Gets the object to be stored in the cache with the given key.
java.lang.Object[]	getCacheElements(java.lang.Object[] pKeys) Returns the array of elements corresponding to the given array of keys, in the same order as the keys in the input array.
int	getCacheElementSize(java.lang.Object pElement, java.lang.Object pKey) Determines the approximate size in bytes of the given cache element.
int	getCacheKeySize(java.lang.Object pKey) Determines the approximate size in bytes of the given cache key.
java.lang.String	getDelimiter()
InventoryManager	getUncachedInventoryManager() Get property UncachedInventoryManager
void	removeCacheElement(java.lang.Object pElement, java.lang.Object pKey) This method is called by the synchronized method Cache.remove to allow the adapter to do any related clean up, if necessary, when an element is removed from the cache.

Method Detail

setDelimiter

public void setDelimiter(java.lang.String pDelimiter)

getDelimiter

public java.lang.String getDelimiter()

setUncachedInventoryManager

public void setUncachedInventoryManager(InventoryManager pUncachedInventoryManager)

Set property UncachedInventoryManager

Parameters:

pUncachedInventoryManager - new value to set

getUncachedInventoryManager

public InventoryManager getUncachedInventoryManager()

Get property UncachedInventoryManager

Returns:

UncachedInventoryManager

getCacheElement

public java.lang.Object getCacheElement(java.lang.Object pKey)
                                 throws java.lang.Exception

Gets the object to be stored in the cache with the given key.

Specified by:

getCacheElement in interface CacheAdapter

Parameters:

pKey - the key to get a value for

Returns:

an instanceof CachedInventoryInfo

Throws:

java.lang.Exception - if some form of exception occurs while attempting to retrieve the element (e.g., SQLException). Since the type of exceptions possible depend upon the implementation of the adapter, the interface allows for generic exceptions.

getCacheElements

public java.lang.Object[] getCacheElements(java.lang.Object[] pKeys)
                                    throws java.lang.Exception

Returns the array of elements corresponding to the given array of keys, in the same order as the keys in the input array. If an element cannot be found for any given key, the value returned for that array element should be null.

Specified by:

getCacheElements in interface CacheAdapter

Throws:

java.lang.Exception - if some form of exception occurs while attempting to retrieve the elements (e.g., SQLException). Since the type of exceptions possible depend upon the implementation of the adapter, the interface allows for generic exceptions.

getCacheKeySize

public int getCacheKeySize(java.lang.Object pKey)

Determines the approximate size in bytes of the given cache key.

Specified by:

getCacheKeySize in interface CacheAdapter

getCacheElementSize

public int getCacheElementSize(java.lang.Object pElement,
                      java.lang.Object pKey)

Determines the approximate size in bytes of the given cache element. The key is passed in as well in case the implementation needs it for any reason.

Specified by:

getCacheElementSize in interface CacheAdapter

removeCacheElement

public void removeCacheElement(java.lang.Object pElement,
                      java.lang.Object pKey)

This method is called by the synchronized method Cache.remove to allow the adapter to do any related clean up, if necessary, when an element is removed from the cache. Most adapters will simply implement this as an empty method.

Specified by:

removeCacheElement in interface CacheAdapter
