README .NET datalayer.provider.simple¶

This .NET sample provides some registered nodes to the ctrlX Data Layer tree.

IMPORTANT:

The sample creates and registers all nodes individually, which is recommended for small to medium sized set of nodes to handle. If you're dealing with a large set of nodes (big data provider) or any dynamic node hierarchy, we recommend to use a virtual provider approach, listening just to any wildcarded address ( e.g. myRoot/**) and using self-managed virtual nodes, just returned in OnBrowse() method, which is more efficient.

Please read the Best Practise section in common .NET documentation for more details and recommended samples.

Introduction¶

The sample demonstrates how to provide nodes to ctrlX Data Layer tree. The provider creates nodes with types of int/double/string. Also a complex type encoded by FlatBuffers is provided.

Description¶

The sample demonstrates

How to provide nodes with different data types to ctrlX Data Layer
How to create and provide meta data to nodes
How to provide nodes with read-only or read-write support
How to register a user defined flatbuffers type
