Class UaExpandedNodeId

java.lang.Object

com.prosysopc.ua.UaExpandedNodeId

All Implemented Interfaces:

Comparable<UaExpandedNodeId>

public class UaExpandedNodeId
extends Object
implements Comparable<UaExpandedNodeId>

This class models an OPC UA ExpandedNodeId, but uses "ServerUri" instead of "ServerIndex" and also only has NamespaceUri (instead of also having a NamespaceIndex). NOTE! This class should only be used if there is a possibility of remote NodeId (or an OPC UA API needs ExpandedNodeId), otherwise UaNodeId should be used instead. Important! The ServerUri must always be defined for instances of UaExpandedNodeId, it cannot be null, even for "local ids". If modelling a local ExpandedNodeId, it should be equal to the first entry of the ServerTable.

Method Summary

Modifier and Type	Method and Description
static UaExpandedNodeId[]	arrayFrom(ExpandedNodeId[] nodeIds, ServerTable serverTable, NamespaceTable namespaceTable) Converts an array of ExpandedNodeId to an array ofUaExpandedNodeId in the context of the given NamespaceTable (effectively calling from(ExpandedNodeId, ServerTable, NamespaceTable) for each element).
ExpandedNodeId	asExpandedNodeId(ServerTable serverTable) Converts this UaExpandedNodeId to ExpandedNodeId, throws IllegalArgumentException if the given ServerTable doesnt't contain getServerUri().
int	compareTo(UaExpandedNodeId other)
boolean	equals(Object obj)
static UaExpandedNodeId	from(ExpandedNodeId nodeId, ServerTable serverTable, NamespaceTable namespaceTable) Converts a ExpandedNodeId to UaExpandedNodeId.
static UaExpandedNodeId	from(String serverUri, String namespaceUri, Object value) Returns an UaExpandedNodeId that has the given server uri, namespace uri and value part.
static UaExpandedNodeId	from(UaApplicationURI server, UaNamespace namespace, Object value) Returns an UaExpandedNodeId that has the given server (uri) and namespace (uri) and value part.
IdType	getIdType()
UaNamespace	getNamespace()
String	getNamespaceUri()
UaApplicationURI	getServer()
String	getServerUri()
Object	getValue()
String	getValueAsParseForm() Returns the value as String that can be parsed by #parse(String, String, String).
int	hashCode()
boolean	isLocal(ServerTable serverTable) Returns true if the getServerUri() is the first entry (index 0) in the given ServerTable, false otherwise (even if the entry is missing from the table).
String	toString()

Method Detail

arrayFrom

public static UaExpandedNodeId[] arrayFrom(ExpandedNodeId[] nodeIds,
                                           ServerTable serverTable,
                                           NamespaceTable namespaceTable)

Converts an array of ExpandedNodeId to an array ofUaExpandedNodeId in the context of the given NamespaceTable (effectively calling from(ExpandedNodeId, ServerTable, NamespaceTable) for each element). Returns null if given null array. Throws IllegalArgumentException if any individual element conversion fails.

from

public static UaExpandedNodeId from(ExpandedNodeId nodeId,
                                    ServerTable serverTable,
                                    NamespaceTable namespaceTable)

Converts a ExpandedNodeId to UaExpandedNodeId. The ExpandedNodeId.getServerIndex() must be in the given ServerTable. Throws IllegalArgumentException if it cannot be found.

If the ExpandedNodeId.getNamespaceUri() it is used as the namespace uri, otherwise the ExpandedNodeId.getNamespaceIndex() is resolved from the given NamespaceTable.

Returns null if given null.

from

public static UaExpandedNodeId from(String serverUri,
                                    String namespaceUri,
                                    Object value)

Returns an UaExpandedNodeId that has the given server uri, namespace uri and value part. Throws IllegalArgumentException if any of the given parameters are null. The serverUri must always be defined.

from

public static UaExpandedNodeId from(UaApplicationURI server,
                                    UaNamespace namespace,
                                    Object value)

Returns an UaExpandedNodeId that has the given server (uri) and namespace (uri) and value part. Throws IllegalArgumentException if any of the given parameters are null. The serverUri must always be defined.

asExpandedNodeId

public ExpandedNodeId asExpandedNodeId(ServerTable serverTable)

Converts this UaExpandedNodeId to ExpandedNodeId, throws IllegalArgumentException if the given ServerTable doesnt't contain getServerUri(). The returned ExpandedNodeId does contain the namespace in uri form.
