template<typename T >
virtual void jsonv::extractor_for< T >::extract ( const extraction_context context,
const value from,
void *  into 
) const
inlineoverridevirtual

Extract a the type from a value into a region of memory.

Parameters
contextExtra information to help you decode sub-objects, such as looking up other formats. It also tracks your path in the decoding heirarchy, so any exceptions thrown will have path information in the error message.
fromThe JSON value to extract something from.
intoThe region of memory to create the extracted object in. There will always be enough room to create your object and the alignment of the pointer should be correct (assuming a working alignof implementation).

Implements jsonv::extractor.
