Detailed Description

template<typename T>
class jsonv::adapter_for< T >

An adapter for the type T.

This is a utility class which converts the void*s used in the extractor and serializer interfaces into the more-friendly T.

Member Function Documentation

extract()

template<typename T >

virtual void jsonv::adapter_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

context	Extra 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.
from	The JSON value to extract something from.
into	The 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.

Definition at line 35 of file adapter_for.hpp.

get_type()

template<typename T >

virtual const std::type_info & jsonv::adapter_for< T >::get_type ( ) const

inlineoverridevirtual

Get the run-time type this extractor knows how to extract.

Once this extractor is registered with a formats, it is not allowed to change.

Implements jsonv::extractor.

Definition at line 30 of file adapter_for.hpp.

to_json()

template<typename T >

virtual value jsonv::adapter_for< T >::to_json ( const serialization_context &  context, const void *  from  ) const

inlineoverridevirtual

Create a value from the value in the given region of memory.

Parameters

context	Extra information to help you encode sub-objects for your type, such as the ability to find other formats. It also tracks the progression of types in the encoding heirarchy, so any exceptions thrown will have type information in the error message.
from	The region of memory that represents the C++ value to convert to JSON. The pointer comes as the result of a static_cast<void*>, so performing a static_cast back to your type is okay.

Implements jsonv::serializer.
