Detailed Description

de-serialize objects from JSON using JSMN library

Function Documentation

deserialize_object()

template<class ITER , typename T , typename ... Args>

bool jsoneat::from_json::jsmn::deserialize_object	(	ITER &	it,
		T	pair,
		Args ...	args
	)

variadic function template for de-serializing all members of an object in one call

Template Parameters

ITER	type of iterator class embedded in JsoNeat
T	type of struct (pair) containing a reference to a data-member and the json-key name used for this member
Args	more types of these pairs like T but, which are only different by the type of the data-member referenced

Parameters

it	iterator
pair	the first data-member-reference / json-key pair object
args	rest of the pair objects

Returns

true if all key in JSMN object matched a data-member-reference in the pair objects

take() [1/5]

SIZE	char array size

Parameters

it	JSMN iterator object reference
