Class NodeRef

java.lang.Object

org.opennms.netmgt.graph.api.NodeRef

public class NodeRef
extends Object

Object to reference a node. This can either be done by setting the nodeId or foreignSource AND foreignId fields. If created from an OnmsNode all fields may be populated. Note: This should allow for easier node referencing, however it is no guarantee that the node referenced actually exists.

Method Detail

getNodeId

public Integer getNodeId()

getForeignSource

public String getForeignSource()

getForeignId

public String getForeignId()

matches

public boolean matches(OnmsNode node)

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getVariants

public List<NodeRef> getVariants()

If nodeId, foreignSource and foreignId are set, this returns multiple variants: nodeId and foreignSource/foreignId node refs

from

public static NodeRef from(String nodeRefCriteria)

Creates a new NodeRef object from a string. This can be a nodeId, but also a fs:fid string.

Parameters:

nodeRefCriteria - the criteria

Returns:

the reference to a node

from

public static NodeRef from(String foreignSource,
                           String foreignId)

Explicitly use foreignSource and foreignId to create a NodeRef object.

from

public static NodeRef from(int nodeId,
                           String foreignSource,
                           String foreignId)

Creates a NodeRef with all fields populated

from

public static NodeRef from(int nodeId)

Creates a NodeRef with only the nodeId field set.

from

public static List<NodeRef> from(GenericVertex vertex)

Creates NodeRefs from a GenericVertex. If multiple properties are set, they are returned in the following order: - reference defined by node id - reference defined by foreignSource/foreignId - reference defined by node criteria string
