JSON AppendArrayCopy Example

Demonstrates the AppendArrayCopy function.

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

Swift

func chilkatTest() {
    let json = CkoJsonObject()!
    json.load(json: "{ \"name\": \"John\", \"marbles\": 100 }")

    let jarr = CkoJsonArray()!
    jarr.load(jsonArray: "[ 1, 2, 3, \"apple\", \"orange\", [ 10, 20, 30 ], { \"name\": \"Alfred\"} ]")

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

    print("\(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.addInt(at: -1, value: 2020)
    print("\(jarr.emit()!)")
    // Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"},2020]

    print("\(json.emit()!)")
    // Remains unchanged: {"name":"John","marbles":100,"stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Alfred"}]}
