Class SegmentNodeBuilder

java.lang.Object

org.apache.jackrabbit.oak.plugins.memory.MemoryNodeBuilder

org.apache.jackrabbit.oak.segment.SegmentNodeBuilder

All Implemented Interfaces:

NodeBuilder

public class SegmentNodeBuilder
extends MemoryNodeBuilder

A node builder that keeps track of the number of updates (set property calls and so on). If there are too many updates, getNodeState() is called, which will write the records to the segment, and that might persist the changes (if the segment is flushed).

protected MemoryNodeBuilder	createChildBuilder(String name) Factory method for creating new child state builders.
SegmentNodeState	getNodeState() Returns an immutable node state that matches the current state of the builder.

Method Detail

updated

protected void updated()

Description copied from class: MemoryNodeBuilder

Called whenever this node is modified, i.e. a property is added, changed or removed, or a child node is added or removed. Changes inside child nodes or the subtrees below are not reported. The default implementation triggers an MemoryNodeBuilder.updated() call on the root builder (unless this is already the root builder), which subclasses can use to capture aggregate update information across the whole tree.

Overrides:

updated in class MemoryNodeBuilder

getNodeState

@Nonnull
public SegmentNodeState getNodeState()

Description copied from interface: NodeBuilder

Returns an immutable node state that matches the current state of the builder.

Specified by:

getNodeState in interface NodeBuilder

Overrides:

getNodeState in class MemoryNodeBuilder

Returns:

immutable node state

createChildBuilder

protected MemoryNodeBuilder createChildBuilder(String name)

Description copied from class: MemoryNodeBuilder

Factory method for creating new child state builders. Subclasses may override this method to control the behavior of child state builders.

Overrides:

createChildBuilder in class MemoryNodeBuilder

Returns:

new builder

createBlob

public Blob createBlob(InputStream stream)
                throws IOException

Specified by:

createBlob in interface NodeBuilder

Overrides:

createBlob in class MemoryNodeBuilder

Throws:

IOException
