JSON AppendArrayCopy Example

Demonstrates the AppendArrayCopy function.

Note: This example requires Chilkat v9.5.0.82 or above.

C

#include <C_CkJsonObject.h>
#include <C_CkJsonArray.h>

void ChilkatSample(void)
    {
    HCkJsonObject json;
    HCkJsonArray jarr;

    json = CkJsonObject_Create();
    CkJsonObject_Load(json,"{ \"name\": \"John\", \"marbles\": 100 }");

    jarr = CkJsonArray_Create();
    CkJsonArray_Load(jarr,"[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]");

    //  Copy the contents of jar to a new array member named "stuff".
    CkJsonObject_AppendArrayCopy(json,"stuff",jarr);

    printf("%s\n",CkJsonObject_emit(json));
    //  Expected output is:  {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}

    //  Note: The contents of the array were copied.
    //  If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
    //  For example:
    CkJsonArray_AddIntAt(jarr,-1,2020);
    printf("%s\n",CkJsonArray_emit(jarr));
    //  Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

    printf("%s\n",CkJsonObject_emit(json));
    //  Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}


    CkJsonObject_Dispose(json);
    CkJsonArray_Dispose(jarr);

    }
