Detailed Description

HazelcastJsonValue is a wrapper for Json formatted strings.

It is preferred to store HazelcastJsonValue instead of std::string for Json formatted strings. Users can run predicates and use indexes on the attributes of the underlying Json strings.

HazelcastJsonValue is queried using Hazelcast's querying language. See query::Predicate.

In terms of querying, numbers in Json strings are treated as either

int64_t 

or

double 

. Strings, bools and NULL are treated as their C++ counterparts.

HazelcastJsonValue keeps given string as it is.
