AllowedMessageSecurityModes Property (UAEndpointSelectionPolicy)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.Engine Namespace > UAEndpointSelectionPolicy Class : AllowedMessageSecurityModes Property
Specifies which message security modes are allowed.
Syntax
'Declaration
 
Public Property AllowedMessageSecurityModes As UAMessageSecurityModes
'Usage
 
Dim instance As UAEndpointSelectionPolicy
Dim value As UAMessageSecurityModes
 
instance.AllowedMessageSecurityModes = value
 
value = instance.AllowedMessageSecurityModes
public UAMessageSecurityModes AllowedMessageSecurityModes {get; set;}
public:
property UAMessageSecurityModes AllowedMessageSecurityModes {
   UAMessageSecurityModes get();
   void set (    UAMessageSecurityModes value);
}

Property Value

Because there is an implicit conversion from UAMessageSecurityModes to UAEndpointSelectionPolicy, you can simply use the returned UAMessageSecurityModes in any place where UAEndpointSelectionPolicy is expected as input, and the corresponding endpoint selection policy will be constructed automatically from the message security modes. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUAMessageSecurityModes static method instead.

Exceptions
ExceptionDescription

An invalid enumeration value was used.

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

Example values:

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated equals to false), access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of static OpcLabs.EasyOpc.UA.EasyUAClientCore.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated to true, you need to access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.IsolatedParameters.

Alternatively, you can override the endpoint selection policy for a specific endpoint by setting it to a non-null value in OpcLabs.EasyOpc.UA.UAEndpointDescriptor.EndpointSelectionPolicy.
