All Implemented Interfaces:

Batch, ChangeLog

public class ConsolidatingChangeLog
extends ChangeLogImpl

A ChangeLog implementation which does basic consolidation on its Operations. That is, cancelling operations are removed if possible. In general this is not possible across move operations. The individual CancelableOperation implementations document their behavior concerning cancellation.

Nested Class Summary

protected static interface	ConsolidatingChangeLog.CancelableOperation This class represent an Operation which can be cancelled by another operation or which cancels another operation.
protected static class	ConsolidatingChangeLog.CancelableOperations Factory for creating CancelableOperations.

Constructor Summary

ConsolidatingChangeLog()

Method Summary

void	addNode(NodeId parentId, Name nodeName, Name nodetypeName, String uuid) Add a new node to the persistent layer.
protected void	addOperation(Operation op) Determines the cancellation behavior from the list of operations and the current operation op: When the current operation is cancelled by the last operation, the list of operations is not modified.
void	addProperty(NodeId parentId, Name propertyName, QValue value) Add a new property to the persistent layer.
void	addProperty(NodeId parentId, Name propertyName, QValue[] values) Add a new multi-valued property to the persistent layer.
protected static Path	getPath(ItemId itemId) Determine the Path from an ItemId.
protected static Path	getPath(NodeId parentId, Name name) Create a Path from the NodeId of a parent and the Name of a child.
void	move(NodeId srcNodeId, NodeId destParentNodeId, Name destName) Move the node identified by the given srcNodeId to the new parent identified by destParentNodeId and change its name to destName.
void	remove(ItemId itemId) Remove an existing item.
void	reorderNodes(NodeId parentId, NodeId srcNodeId, NodeId beforeNodeId) Modify the order of the child nodes identified by the given NodeIds.
void	setMixins(NodeId nodeId, Name[] mixinNodeTypeNames) Modify the set of mixin node types present on the node identified by the given id.
