C++ datalayer.register.node example with other datatypes

[LunatiX]

I'm able to register new FLOAT nodes inside the datalayer with the C++ example (datalayer.register.node) from SDK. But how can I register other datatypes like STRING, INT, DOUBLE?

Could someone provide a detailed example? This would be very usefull to provide a good example for customers presentation.

Hi slu2but,

basically you register a provider, in this example the provider contains a float value and you are able to set the value to another float.

The datatype provided by your node ist a variant. All these types are possible:

  //! Types for Variant

typedef enum class VariantType {

UNKNOWN,            //! unknown data type

BOOL8,              //! bool 8 bit

INT8,               //! signed int 8 bit

UINT8,              //! unsigned int 8 bit

INT16,              //! signed int 16 bit

UINT16,             //! unsigned int 16 bit

INT32,              //! signed int 32 bit

UINT32,             //! unsigned int 32 bit

INT64,              //! signed int 64 bit

UINT64,             //! unsigned int 64 bit

FLOAT32,            //! float 32 bit

FLOAT64,            //! float 64 bit

STRING,             //! string (UTF-8)

ARRAY_OF_BOOL8,     //! array of bool 8 bit

ARRAY_OF_INT8,      //! array of signed int 8 bit

ARRAY_OF_UINT8,     //! array of unsigned int 8 bit

ARRAY_OF_INT16,     //! array of signed int 16 bit

ARRAY_OF_UINT16,    //! array of unsigned int 16 bit

ARRAY_OF_INT32,     //! array of signed int 32 bit

ARRAY_OF_UINT32,    //! array of unsigned int 32 bit

ARRAY_OF_INT64,     //! array of signed int 64 bit

ARRAY_OF_UINT64,    //! array of unsigned int 64 bit

ARRAY_OF_FLOAT32,   //! array of float 32 bit

ARRAY_OF_FLOAT64,   //! array of float 64 bit

ARRAY_OF_STRING,    //! array of string (UTF-8)

RAW,                //! raw bytes

FLATBUFFERS,        //! bytes as a complex data type encoded as a flatbuffer

}VariantType;

In your example the m_value variable is a float, its also possible to use other variables.

Hello,

here is the newest version of the example register.node. This will be included in the next release.

Includes string, float and integer.

Now I'm using the SDK Version 1.0.0-develop.144 and with that it's possible to write other datatypes to the datalayer. Thanks
