Detailed Description

Functions that can be used to optimize common operations in a NodeManager.

Member Function Documentation

Node UnifiedAutomation.UaServer.IAdvancedNodeManager.GetNodeAttributes	(	RequestContext	context,
		BrowseHandle	browseHandle,
		NodeClass	expectedNodeClass
	)

Gets the node attributes.

Parameters

context	The request context.
browseHandle	The browse handle.
expectedNodeClass	The expected node class.

Returns

The subtype of Node depending on the NodeClass. null if the node is not the expected node class.

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.

NodeMetadata UnifiedAutomation.UaServer.IAdvancedNodeManager.GetNodeMetadata	(	RequestContext	context,
		BrowseHandle	browseHandle,
		NodeMetadataMask	fieldsToReturn,
		NodeClass	nodeClassFilter
	)

Gets the node metadata.

Parameters

context	The request context.
browseHandle	The browse handle.
fieldsToReturn	The fields to return.
nodeClassFilter	The node class filter.

Returns

The metadata with only the requested fields. null if the node does not have the requested node class.

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.

DataValue UnifiedAutomation.UaServer.IAdvancedNodeManager.ReadAttribute	(	RequestContext	context,
		NodeAttributeHandle	nodeHandle
	)

Reads the attribute.

Parameters

context	The request context.
nodeHandle	The node handle.

Returns

The value of the requested attribute. Returns null if the attribute cannot be read with this method (meaning the I/O manager needs to be used).

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.

T UnifiedAutomation.UaServer.IAdvancedNodeManager.ReadValue< T >	(	RequestContext	context,
		NodeAttributeHandle	nodeHandle,
		QualifiedName	componentName,
		T	defaultValue
	)

Reads the attribute value for a child node.

Template Parameters

T	The data type of the attribute to read.

Parameters

context	The request context.
nodeHandle	The node handle.
componentName	Name of the component.
defaultValue	The default value.

Returns

The value of the variable identified by the component name. The defaultValue if any error occurs.

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.

T UnifiedAutomation.UaServer.IAdvancedNodeManager.ReadValue< T >	(	RequestContext	context,
		NodeAttributeHandle	nodeHandle,
		QualifiedName[]	browsePath,
		T	defaultValue
	)

Reads the attribute value for a child node.

Template Parameters

T	The data type of the value to read.

Parameters

context	The request context.
nodeHandle	The node handle.
browsePath	The browse path.
defaultValue	The default value.

Returns

The value of the variable identified by the browse path. The defaultValue if any error occurs.

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.

StatusCode UnifiedAutomation.UaServer.IAdvancedNodeManager.WriteAttribute	(	RequestContext	context,
		NodeAttributeHandle	nodeHandle,
		Variant	valueToWrite
	)

Writes the attribute.

Parameters

context	The request context.
nodeHandle	The node handle.
valueToWrite	The value to write.

Returns

Writes the attribute. Returns null if the attribute cannot be written with this method (meaning the I/O manager needs to be used).

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.

StatusCode UnifiedAutomation.UaServer.IAdvancedNodeManager.WriteValue	(	RequestContext	context,
		NodeAttributeHandle	nodeHandle,
		QualifiedName	componentName,
		Variant	valueToWrite
	)

Writes the attribute value for a child node.

Parameters

context	The request context.
nodeHandle	The node handle.
componentName	Name of the component.
valueToWrite	The value to write.

Returns

The result of the operation.

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.

StatusCode UnifiedAutomation.UaServer.IAdvancedNodeManager.WriteValue	(	RequestContext	context,
		NodeAttributeHandle	nodeHandle,
		QualifiedName[]	browsePath,
		Variant	valueToWrite
	)

Writes the attribute value for a child node.

Parameters

context	The request context.
nodeHandle	The node handle.
browsePath	The browse path.
valueToWrite	The value to write.

Returns

The result of the operation.

Implemented in UnifiedAutomation.UaServer.BaseNodeManager.
