Method Detail

enter

public void enter(NodeState before,
                  NodeState after)
           throws CommitFailedException

Description copied from interface: Editor

Called before the given before and after states are compared. The implementation can use this method to initialize any internal state needed for processing the results of the comparison. For example an implementation could look up the effective node type of the after state to know what constraints to apply to on the content changes.

Specified by:

enter in interface Editor

Parameters:

before - before state, non-existent if this node was added

after - after state, non-existent if this node was removed

Throws:

CommitFailedException - if this commit should be rejected

isReindexingPerformed

public boolean isReindexingPerformed()

getReindexStats

public java.util.List<java.lang.String> getReindexStats()

getUpdatedIndexPaths

public java.util.Set<java.lang.String> getUpdatedIndexPaths()

setTraversalRateEstimator

public void setTraversalRateEstimator(org.apache.jackrabbit.oak.plugins.index.progress.TraversalRateEstimator estimator)

setNodeCountEstimator

public void setNodeCountEstimator(org.apache.jackrabbit.oak.plugins.index.progress.NodeCountEstimator nodeCountEstimator)

getIndexingStats

public java.lang.String getIndexingStats()

setIgnoreReindexFlags

public void setIgnoreReindexFlags(boolean ignoreReindexFlag)

getPath

public java.lang.String getPath()

Returns the path of this node, building it lazily when first requested.

Specified by:

getPath in interface NodeTraversalCallback.PathSource

leave

public void leave(NodeState before,
                  NodeState after)
           throws CommitFailedException

Description copied from interface: Editor

Called after the given before and after states are compared. The implementation can use this method to post-process information collected during the content diff. For example an implementation that during the diff just recorded the fact that this node was modified in some way could then use this method to trigger an index update based on that modification flag.

Specified by:

leave in interface Editor

Parameters:

before - before state, non-existent if this node was added

after - after state, non-existent if this node was removed

Throws:

CommitFailedException - if this commit should be rejected

propertyAdded

public void propertyAdded(PropertyState after)
                   throws CommitFailedException

Description copied from interface: Editor

Processes an added property.

Specified by:

propertyAdded in interface Editor

Parameters:

after - the added property

Throws:

CommitFailedException - if processing failed

propertyChanged

public void propertyChanged(PropertyState before,
                            PropertyState after)
                     throws CommitFailedException

Description copied from interface: Editor

Processes a changed property.

Specified by:

propertyChanged in interface Editor

Parameters:

before - the original property

after - the changed property

Throws:

CommitFailedException - if processing failed

propertyDeleted

public void propertyDeleted(PropertyState before)
                     throws CommitFailedException

Description copied from interface: Editor

Processes a removed property.

Specified by:

propertyDeleted in interface Editor

Parameters:

before - the removed property

Throws:

CommitFailedException - if processing failed

childNodeAdded

@NotNull
public @NotNull Editor childNodeAdded(java.lang.String name,
                                               NodeState after)
                                        throws CommitFailedException

Description copied from interface: Editor

Processes an added child node.

Specified by:

childNodeAdded in interface Editor

Parameters:

name - name of the added node

after - the added child node

Returns:

an editor for processing the subtree below the added node, or null if the subtree does not need processing

Throws:

CommitFailedException - if processing failed

childNodeChanged

@NotNull
public @NotNull Editor childNodeChanged(java.lang.String name,
                                                 NodeState before,
                                                 NodeState after)
                                          throws CommitFailedException

Specified by:

childNodeChanged in interface Editor

Parameters:

name - name of the changed node

before - child node before the change

after - child node after the change

Returns:

an editor for processing the subtree below the added node, or null if the subtree does not need processing

                                                   NodeState before)
                                            throws CommitFailedException
