JSON AppendArrayCopy Example

Demonstrates the AppendArrayCopy function.

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

Objective-C

#import <CkoJsonObject.h>
#import <CkoJsonArray.h>

CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json Load: @"{ \"name\": \"John\", \"marbles\": 100 }"];

CkoJsonArray *jarr = [[CkoJsonArray alloc] init];
[jarr Load: @"[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]"];

//  Copy the contents of jar to a new array member named "stuff".
[json AppendArrayCopy: @"stuff" jarr: jarr];

NSLog(@"%@",[json Emit]);
//  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:
[jarr AddIntAt: [NSNumber numberWithInt: -1] value: [NSNumber numberWithInt: 2020]];
NSLog(@"%@",[jarr Emit]);
//  Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

NSLog(@"%@",[json Emit]);
//  Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}
