Detailed Description

Stores metadata heterogeneous type value.

This interfaces only give access to the type of data stored, and how many of elements are stored. Values can be accessed by casting the raw pointer to the corresponding type.

Member Function Documentation

raw()

virtual const void* iolink::VariantDataValue::raw ( ) const

pure virtual

Returns a pointer to the location where all the values are stored continuously.

To ease raw value decoding, a helper called VariantDataValueConverter is available to simply convert this VariantDataValue to basic types.
