Parameters

client

The client object that will perform the operation.

This is typically the EasyUAClient object.

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

serverCapabilityFilter

List of Server capability filters. Only records with all the specified server capabilities are returned.

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

discoveryHost

The name of the machine that runs the discovery server that will be used for discovery task.

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

flat

Determines whether one element will be returned for each discovery URI.

Return Value

When the flat parameter is false, the discovery query returns one OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement for each application found, and its OpcLabs.EasyOpc.UA.Discovery.IUAReadOnlyApplicationElement.DiscoveryUriStrings property contains one or more application discovery URLs.

When the flat parameter is true, the discovery query returns one OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement for each discovery URL of each application found. In this case, the OpcLabs.EasyOpc.UA.Discovery.IUAReadOnlyApplicationElement.DiscoveryUriStrings property of each returned application element contains precisely one string, and you can therefore use the OpcLabs.EasyOpc.UA.Discovery.IUAReadOnlyApplicationElement.DiscoveryUriString property instead to obtain the discovery URL.

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.
