Method Detail

getAttributes

public NodeAttributes getAttributes()

Description copied from interface: UaNode

Returns the current attribute values of the node in a NodeAttributes structure.

Specified by:

getAttributes in interface UaNode

getDataTypeDefinition

public DataTypeDefinition getDataTypeDefinition()

Description copied from interface: UaDataType

Get the DataTypeDefinition Attribute value. Note! this Attribute was added in UA 1.04, earlier servers do not support this, in which case this method returns null. Additionally this Attribute is only supported on Enumeration, Structure and sub-types of UInteger types defining OptionSet-like semantics.

Per specification 1.04 Part 3, for Enumeration, UInteger sub-types having OptionSet semantics and subtypes of the OptionSet Structure this should return EnumDefinition. For other Structure types StructureDefinition should be returned.

Specified by:

getDataTypeDefinition in interface UaDataType

getNodeClass

public final NodeClass getNodeClass()

Description copied from interface: UaNode

The NodeClass Attribute identifies the NodeClass of a Node.

Specified by:

getNodeClass in interface UaNode

Overrides:

getNodeClass in class UaNodeImpl

Returns:

the Node Class of the node. This is hard-coded and cannot be changed.

setAttributes

public void setAttributes(DataTypeAttributes dataTypeAttributes)

supportsAttribute

public boolean supportsAttribute(UnsignedInteger attributeId)

Description copied from interface: UaNode

Check if the node supports the specified attribute.

Use the method to check if the node object you have is actually supporting a specific UA Attribute. The supported attributes are available from specific Java properties, and the values can also be read with UaNode.readAttribute(com.prosysopc.ua.stack.builtintypes.UnsignedInteger).

Specified by:

supportsAttribute in interface UaNode

Overrides:

supportsAttribute in class UaNodeImpl

Parameters:

attributeId - the attribute to check - the valid values are defined in Attributes

Returns:

true if the node supports the attribute

getAttributes

protected DataTypeAttributes getAttributes(DataTypeAttributes attributes)

getAttributesMap

protected void getAttributesMap(Map<UnsignedInteger,Object> map)

Overrides:

getAttributesMap in class UaNodeImpl

initSupportedAttributes

protected void initSupportedAttributes(List<UnsignedInteger> l)

Overrides:

initSupportedAttributes in class UaTypeImpl

readAttributeValue

protected void readAttributeValue(UnsignedInteger attributeId,
                                  DataValue dataValue)
                           throws StatusException

Description copied from class: UaNodeImpl

Read the value of an attribute.

Overrides:

readAttributeValue in class UaTypeImpl

Parameters:

attributeId - the ID of the attribute to read.

dataValue - the DataValue structure in which the value is set.

Throws:

StatusException - on failure

writeAttributeValue

protected void writeAttributeValue(UnsignedInteger attributeId,
                                   Object value,
                                   StatusCode statusCode,
                                   DateTime sourceTime,
                                   UnsignedShort sourcePicoseconds)
                            throws StatusException

Overrides:

writeAttributeValue in class UaTypeImpl

Throws:

StatusException
