RegisterMultipleNodes Method (IEasyUAClientNodeRegistration)

Registers the nodes specified by an array of node arguments (endpoint descriptor and node descriptor in each arguments object).

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
Function RegisterMultipleNodes( _
   ByVal nodeArgumentsArray() As UANodeArguments _
) As Integer()

'Usage
 
Dim instance As IEasyUAClientNodeRegistration
Dim nodeArgumentsArray() As UANodeArguments
Dim value() As Integer
 
value = instance.RegisterMultipleNodes(nodeArgumentsArray)

[NotNull()]
int[] RegisterMultipleNodes( 
   UANodeArguments[] nodeArgumentsArray
)

[NotNull()]
array<int>^ RegisterMultipleNodes( 
   array<UANodeArguments^>^ nodeArgumentsArray
)

Parameters

nodeArgumentsArray

An array of node arguments for nodes that should be registered.

The value of this parameter cannot be null (Nothing in Visual Basic).

The individual elements of the parameter value cannot be null (Nothing in Visual Basic).

Return Value

Returns an array of integer handles that can be used for unregistering the nodes. Indexes in the returned array correspond with indexes in the .

This method never returns null (Nothing in Visual Basic).

Exceptions

Exception Description

Exception	Description
System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

System.ArgumentNullException

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

The method may perform the registration asynchronously.

Example

VB.NET
Python
