Detailed Description

Figures out relations between objects, nodes and classes for cache management.

This class works together with eZContentCache to manage the cache files for content viewing. This class takes care of finding out the relationship and then passes a list of nodes to eZContentCache which does the actual clearing.

The manager uses special rules in 'viewcache.ini' to figure relationships.

static eZContentCacheManager::nodeList	(	$	objectID,
		$	versionNum
	)		`[static]`

Figures out all nodes that are affected by the change of object $objectID. This involves finding all nodes, parent nodes and nodes of objects that relate this object. The 'viewcache.ini' file is also checked to see if some special content classes has dependencies to the current object, if this is true extra nodes might be included.

Parameters:

$versionNum	The version of the object to use or `true` for current version
$additionalNodeList	An array with node IDs to add to clear list, or `false` for no additional nodes.

Returns:: An array with node IDs that must have their viewcaches cleared.

static eZContentCacheManager::nodeListForObject	(	$	contentObject,
		$	versionNum,

		&$	nodeList,
		&$	handledObjectList
	)		`[static]`

Use $clearCacheType to include different kind of nodes( parent, relating, etc ). If $versionNum is true, then current version will be used.

Parameters:

	$contentObject	Current content object that is checked.
	$versionNum	The version of the object to use or `true` for current version
	$clearCacheType	Bit field which controls the the extra nodes to include, use bitwise or with one of these defines: self::CLEAR_NODE_CACHE - Clear the nodes of the object self::CLEAR_PARENT_CACHE - Clear the parent nodes of the object self::CLEAR_RELATING_CACHE - Clear nodes of objects that relate this object self::CLEAR_KEYWORD_CACHE - Clear nodes of objects that have the same keyword as this object self::CLEAR_SIBLINGS_CACHE - Clear caches for siblings of the node. self::CLEAR_ALL_CACHE - Enables all of the above self::CLEAR_NO_CACHE - Do not clear cache for current object.
[out]	$nodeList	An array with node IDs that are affected by the current object change.
[out]	$handledObjectList	An associative array with object IDs and the cache types that were handled for these objects already. Used to avoid infinite recursion.
