Methods

RegisterNodes

2 overloads

Overload	Description
RegisterNodes(IEnumerable<OpcRegisterNode>)	Registers one or more nodes for optimized node access using the specified commands.
RegisterNodes(params OpcRegisterNode[])	Registers one or more nodes for optimized node access using the specified commands.

Known results: BadNodeIdInvalid

Exceptions (all overloads)

Exception	Condition
ArgumentNullException	The commands sequence or one of its items is a null reference (Nothing in Visual Basic).
InvalidOperationException	The register nodes service is currently not supported, especially using the commands specified.
OpcException	The service execution failed upon different circumstances; for more details see exception details. The following issues can lead to that exception: BadNothingToDo and BadTooManyMatches.

RegisterNodes(IEnumerable<OpcRegisterNode>)

Registers one or more nodes for optimized node access using the specified commands.

OpcNodeIdCollection RegisterNodes(IEnumerable<OpcRegisterNode> commands)

Function RegisterNodes(
    commands As IEnumerable(Of OpcRegisterNode)) As OpcNodeIdCollection

Parameters

Name	Type	Description
commands	IEnumerable<OpcRegisterNode>	A sequence of OpcRegisterNode instances to process.

Returns

OpcNodeIdCollection

A collection of OpcNodeId instances its number and order of items matches the number and order of items in the commands sequence. There is for each command one entry which stores the node identifier requested by that command to use to access the node registered for optimized node access.

Remarks

Servers completely reject register nodes requests if any of the node identifiers passed are structurally invalid.

RegisterNodes(params OpcRegisterNode[])

Registers one or more nodes for optimized node access using the specified commands.

OpcNodeIdCollection RegisterNodes(params OpcRegisterNode[] commands)

Function RegisterNodes(
    ParamArray commands As OpcRegisterNode()) As OpcNodeIdCollection

Parameters

Name	Type	Description
commands	params OpcRegisterNode[]	An array of of OpcRegisterNode instances to process.

Returns

OpcNodeIdCollection

A collection of OpcNodeId instances its number and order of items matches the number and order of items in the commands sequence. There is for each command one entry which stores the node identifier requested by that command to use to access the node registered for optimized node access.

Remarks

Servers completely reject register nodes requests if any of the node identifiers passed are structurally invalid.
