java.lang.Object

com.graphaware.common.representation.DetachedEntity<ID,Node>

com.graphaware.common.representation.DetachedNode<ID>

com.graphaware.common.representation.SerializableNode<ID>

Type Parameters:

ID - type of custom node ID.

All Implemented Interfaces:

DetachedNodeExpressions, EntityExpressions, Serializable

Direct Known Subclasses:

JsonNode

public class SerializableNode<ID>
extends DetachedNode<ID>

Constructor Detail

SerializableNode

public SerializableNode()

Public no-arg constructor (for Jackson et. al.)

SerializableNode

public SerializableNode(Node node,
                        NodeIdTransformer<ID> transformer)

Create a Serializable DetachedNode from a Neo4j node. All properties will be included.

Parameters:

node - node to create the representation from.

transformer - ID transformer.

SerializableNode

public SerializableNode(Node node,
                        String[] properties,
                        NodeIdTransformer<ID> transformer)

Create a Serializable DetachedNode from a Neo4j node.

Parameters:

node - node to create the representation from. Must not be null.

properties - keys of properties to be included in the representation. Can be null, which represents all. Empty array represents none.

transformer - ID transformer.

SerializableNode

public SerializableNode(ID id)

Create a Serializable DetachedNode from custom node ID.

Parameters:

id - custom ID of the node. Can be null to represent a new node.

SerializableNode

public SerializableNode(ID id,
                        String[] labels,
                        Map<String,Object> properties)

Construct Serializable DetachedNode of a node.

Parameters:

id - custom ID of the node. Can be null to represent a new node.

labels - of the new node representation.

properties - of the new node representation.

Method Detail

produceEntity

public Node produceEntity(Transaction tx,
                          NodeIdTransformer<ID> transformer)

Produce a Node from this representation. This means either fetch the node from the given tx (iff id is set), or create it.

Parameters:

tx - to create/fetch node in.

transformer - ID transformer.

Returns:

node.

getId

public ID getId()

Specified by:

getId in class DetachedEntity<ID,Node>

setId

public void setId(ID id)

equals

public boolean equals(Object o)

Overrides:

equals in class DetachedNode<ID>

hashCode

public int hashCode()

Overrides:

hashCode in class DetachedNode<ID>
