Constructor Detail

IncrementalFlatFileStoreEditor

public IncrementalFlatFileStoreEditor(BufferedWriter bufferedWriter,
                                      IncrementalFlatFileStoreNodeStateEntryWriter entryWriter,
                                      Predicate<String> predicate,
                                      IncrementalFlatFileStoreStrategy incrementalFlatFileStoreStrategy,

Method Detail

enter

public void enter(NodeState before,
                  NodeState after)

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

leave

public void leave(NodeState before,
                  NodeState after)

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

propertyAdded

public void propertyAdded(PropertyState after)

Description copied from interface: Editor

Processes an added property.

Specified by:

propertyAdded in interface Editor

Parameters:

after - the added property

propertyChanged

public void propertyChanged(PropertyState before,
                            PropertyState after)

Description copied from interface: Editor

Processes a changed property.

Specified by:

propertyChanged in interface Editor

Parameters:

before - the original property

after - the changed property

propertyDeleted

public void propertyDeleted(PropertyState before)

Description copied from interface: Editor

Processes a removed property.

Specified by:

propertyDeleted in interface Editor

Parameters:

before - the removed property

childNodeAdded

@Nullable
public @Nullable Editor childNodeAdded(String name,
                                       NodeState after)

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

childNodeChanged

@Nullable
public @Nullable Editor childNodeChanged(String name,
                                         NodeState before,
                                         NodeState after)

Description copied from interface: Editor

Processes a changed child node. This method gets called for all child nodes that may contain changes between the before and after states.

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

childNodeDeleted

@Nullable
public @Nullable Editor childNodeDeleted(String name,
                                         NodeState before)

Description copied from interface: Editor

Processes a deleted child node.

Specified by:

childNodeDeleted in interface Editor

Parameters:

name - name of the deleted node

before - the deleted child node

Returns:

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