NAME

Alzabo::ObjectCache::MemoryStore - Cache objects in memory

SYNOPSIS

  use Alzabo::ObjectCache( store => 'Alzabo::ObjectCache::MemoryStore',
                           sync  => 'Alzabo::ObjectCache::NullSync' );

DESCRIPTION

This class simply stores cached objects in memory. This means that a given object should never have to be created twice.

METHODS

Note that pretty much all the methods that take an object as an argument will silently do nothing if the object is not already in the cache. The obvious exception is the store_object method.

Many of the methods in this class really don't do anything and are here merely to support the interface that Alzabo::Runtime::Row expects.

new

Returns

A new Alzabo::ObjectCache::MemoryStore object.

fetch_object ($id)

Returns

The specified object if it is in the cache. Otherwise it returns undef.

store_object ($object)

Stores an object in the cache. This will not overwrite an existing object in the cache. To do that you must first call the delete_from_cache method.

delete_from_cache ($object)

This method allows you to remove an object from the cache. This does not register the object as deleted. It is provided solely so that you can call store_object after calling this method and have store_object actually store the new object.

CLASS METHOD

clear

Call this method to completely clear the cache.
