OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.DataTypeModel.ComTypes Namespace > _UADataTypeDefinitionProvider Interface : GetDataTypeInfoFromDataTypeId Method
A data type ID.

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

Determines whether the provider will attempt to recursively look at supertypes when determining the data type info.
Determines whether base data types will always be included in the result.
In DataTypeDefinition model, gets a data type info from given data type ID.

Parameters

dataTypeId
A data type ID.

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

searchSupertypes
Determines whether the provider will attempt to recursively look at supertypes when determining the data type info.
requireBaseDataType
Determines whether base data types will always be included in the result.

Return Value

A value result with the data type info obtained.

This method can return null (Nothing in Visual Basic).

Remarks

Success result with null value indicates that the data type info is not present for the data type ID.

You can obtain the data type schema provider interface (OpcLabs.EasyOpc.UA.DataTypeModel.IUADataTypeDefinitionProvider) from the OpcLabs.EasyOpc.UA.Plugins.ComplexData.IEasyUAClientComplexData.DataTypeDefinitionProvider property of the OpcLabs.EasyOpc.UA.Plugins.ComplexData.IEasyUAClientComplexData service.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

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.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
