Class InMemoryNode

java.lang.Object
  org.jboss.dna.graph.connector.map.DefaultMapNode
      org.jboss.dna.graph.connector.inmemory.InMemoryNode

All Implemented Interfaces:

MapNode

public class InMemoryNode
extends DefaultMapNode

An MapNode implementation used by the InMemoryRepository.

Nested Class Summary

static interface

InMemoryNode.ChangeListener The interface that InMemoryNode objects use to signal when they are about to change.

Constructor Summary

InMemoryNode(InMemoryNode.ChangeListener listener, UUID uuid)

Method Summary

void	addChild(int index, MapNode child) Inserts the specified child at the specified position in the list of children.
void	addChild(MapNode child) Adds the given child to the end of the list of children for this node
void	clearChildren() Removes all of the children for this node in a single operation.
boolean	removeChild(MapNode child) Removes the given child from the list of children
MapNode	removeProperty(Name propertyName) Removes the property with the given name
void	setName(Path.Segment name)
void	setParent(MapNode parent)
MapNode	setProperties(Iterable<Property> properties) Sets the given properties in a single operation, overwriting any previous properties for the same name This bulk mutator should be used when multiple properties are being set in order to allow underlying implementations to optimize their access to their respective persistent storage mechanism.
MapNode	setProperty(ExecutionContext context, String name, Object... values) Sets the property with the given name, overwriting any previous property for the given name
MapNode	setProperty(Property property) Sets the property with the given name, overwriting any previous property for the given name

Constructor Detail

InMemoryNode

public InMemoryNode(InMemoryNode.ChangeListener listener,
                    UUID uuid)

Parameters:

listener - the listener that is to be notified of any changes

uuid - the UUID of the node

Method Detail

addChild

public void addChild(int index,
                     MapNode child)

Inserts the specified child at the specified position in the list of children. Shifts the child currently at that position (if any) and any subsequent children to the right (adds one to their indices).

Specified by:

addChild in interface MapNode

Overrides:

addChild in class DefaultMapNode

Parameters:

index - index at which the specified child is to be inserted

child - the child to be inserted

See Also:

DefaultMapNode.addChild(int, org.jboss.dna.graph.connector.map.MapNode)

addChild

public void addChild(MapNode child)

Adds the given child to the end of the list of children for this node

Specified by:

addChild in interface MapNode

Overrides:

addChild in class DefaultMapNode

Parameters:

child - the child to add to this node

See Also:

DefaultMapNode.addChild(org.jboss.dna.graph.connector.map.MapNode)

clearChildren

public void clearChildren()

Removes all of the children for this node in a single operation.

Specified by:

clearChildren in interface MapNode

Overrides:

clearChildren in class DefaultMapNode

See Also:

DefaultMapNode.clearChildren()

removeChild

public boolean removeChild(MapNode child)

Removes the given child from the list of children

Specified by:

removeChild in interface MapNode

Overrides:

removeChild in class DefaultMapNode

Parameters:

child - the child to be removed

Returns:

true if the child was one of this node's children (and was removed); false otherwise

See Also:

DefaultMapNode.removeChild(org.jboss.dna.graph.connector.map.MapNode)

removeProperty

public MapNode removeProperty(Name propertyName)

Removes the property with the given name

Specified by:

removeProperty in interface MapNode

Overrides:

removeProperty in class DefaultMapNode

Parameters:

propertyName - the name of the property to remove

Returns:

this map node

See Also:

DefaultMapNode.removeProperty(org.jboss.dna.graph.property.Name)

setName

public void setName(Path.Segment name)

Specified by:

setName in interface MapNode

Overrides:

setName in class DefaultMapNode

Parameters:

name - Sets name to the specified value.

See Also:

DefaultMapNode.setName(org.jboss.dna.graph.property.Path.Segment)

setParent

public void setParent(MapNode parent)

Specified by:

setParent in interface MapNode

Overrides:

setParent in class DefaultMapNode

Parameters:

parent - Sets parent to the specified value.

See Also:

DefaultMapNode.setParent(org.jboss.dna.graph.connector.map.MapNode)

setProperties

public MapNode setProperties(Iterable<Property> properties)

Sets the given properties in a single operation, overwriting any previous properties for the same name This bulk mutator should be used when multiple properties are being set in order to allow underlying implementations to optimize their access to their respective persistent storage mechanism.

Specified by:

setProperties in interface MapNode

Overrides:

setProperties in class DefaultMapNode

Parameters:

properties - the properties to set

Returns:

this map node

See Also:

DefaultMapNode.setProperties(java.lang.Iterable)

setProperty

public MapNode setProperty(ExecutionContext context,
                           String name,
                           Object... values)

Sets the property with the given name, overwriting any previous property for the given name

Specified by:

setProperty in interface MapNode

Overrides:

setProperty in class DefaultMapNode

Parameters:

context - the current execution context, used to get a name factory and property factory.

name - the name of the property

values - the values for the property

Returns:

this map node

See Also:

DefaultMapNode.setProperty(org.jboss.dna.graph.ExecutionContext, java.lang.String, java.lang.Object[])

setProperty

public MapNode setProperty(Property property)

Sets the property with the given name, overwriting any previous property for the given name

Specified by:

setProperty in interface MapNode

Overrides:
