Load a JsonArray

See more JSON Examples

Demonstrates how to load a JsonArray.

Note: This example requires Chilkat v9.5.0.64 or greater.

C++

#include <CkJsonArray.h>
#include <CkJsonObject.h>

void ChilkatSample(void)
    {
    //  This example requires Chilkat v9.5.0.64 or greater.

    //  Loading into a new JSON array is simple and straightforward.
    CkJsonArray a;
    a.Load("[ 1,2,3,4 ]");

    //  Output:  [1,2,3,4]
    std::cout << a.emit() << "\r\n";
    std::cout << "--------" << "\r\n";

    //  The JsonArray's Load and LoadSb methods have a peculiar behavior when
    //  it is already part of a JSON document.  In this case, the JsonArray
    //  becomes detached, and the original document remains unchanged.
    //  This is intentional due to the nature of the internal implementation.
    //  For example:

    CkJsonObject json;
    json.Load("{ \"abc\": [ 1,2,3,4 ] }");

    //  Output:  (json) {"abc":[1,2,3,4]}
    std::cout << "(json) " << json.emit() << "\r\n";
    std::cout << "--------" << "\r\n";

    CkJsonArray *abc = json.ArrayOf("abc");
    //  When Load is called, abc becomes it's own document, and the original is not modified.
    abc->Load("[ 5,6,7,8 ]");

    //  Output: (abc) [5,6,7,8]
    std::cout << "(abc) " << abc->emit() << "\r\n";
    std::cout << "--------" << "\r\n";

    //  Output: (json) {"abc":[1,2,3,4]}
    std::cout << "(json) " << json.emit() << "\r\n";
    std::cout << "--------" << "\r\n";
    delete abc;
    }
