Protected Properties

Property	Type	Description
$factory	jackalope\FactoryInterface	The factory to instantiate objects
$nodesAdd	Jackalope\Transport\AddNodeOperation[]	Keys are the full paths to be added
$nodesMove	Jackalope\Transport\MoveNodeOperation[]	Keys are the source paths, values the move operations containing the target path. The objectsByPath array is updated immediately and any getItem and similar requests are rewritten for the transport layer until save() Only nodes can be moved, not properties. Note: Keep in mind that moving also affects all children of the moved node, but we only have the explicitly moved paths in this array. We check on moved parents whenever retrieving a non-cached node.
$nodesRemove	Jackalope\Transport\RemoveNodeOperation[]	Keys are the full paths to be removed. Note: Keep in mind that a delete is recursive, but we only have the explicitly deleted paths in this array. We check on deleted parents whenever retrieving a non-cached node.
$objectsByPath	array	There is no notion of order here. The order is defined by order in the Node::nodes array.
$objectsByUuid	array	Take care never to put a path in here unless there is a node for that path in objectsByPath.
$operationsLog	Jackalope\Transport\Operation[]	Add, remove and move actions need to be saved in the correct order to avoid i.e. adding something where a node has not yet been moved to.
$propertiesRemove	Jackalope\Transport\RemovePropertyOperation[]	Keys are the full paths of properties to be removed.
$session	PHPCR\SessionInterface
$transport	Jackalope\Transport\TransportInterface
