Detailed Description

hazelcast_json_value is a wrapper for Json formatted strings.

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

hazelcast_json_value 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.

hazelcast_json_value keeps given string as it is.

Constructor & Destructor Documentation

◆ hazelcast_json_value()

hazelcast::client::hazelcast_json_value::hazelcast_json_value ( std::string json_string )

Create a hazelcast_json_value from a string.

This method does not the check validity of the underlying Json string. Invalid Json strings may cause wrong results in queries.

Parameters

jsonString The json string

Returns: The hazelcast_json_value representing the json string.
