Detailed Description

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

An extractor for a type T with an extracting constructor.

Four constructor shapes are accepted, preferred in this order: T(reader&, extraction_context&), T(reader&), T(const value&, extraction_context&) and T(const value&). The last two are the shapes which predate extraction running off a reader; they are handed a subtree materialised by read_value, so they keep working but pay for the tree they were always paying for.
