Class JsonList

java.lang.Object

java.util.AbstractCollection<Object>

java.util.AbstractList<Object>

java.util.ArrayList<Object>

com.webfirmframework.wffweb.json.JsonList

All Implemented Interfaces:

JsonBaseNode, JsonListNode, JsonPart, Serializable, Cloneable, Iterable<Object>, Collection<Object>, List<Object>, RandomAccess, SequencedCollection<Object>

public non-sealed class JsonList
extends ArrayList<Object>
implements JsonListNode, Serializable

To parse json array string:

    JsonListNode jsonList = JsonList.parse("[1, 4, 0, 1]");

    //To get the value from an index
    int intValueAt1 = jsonList.getValueAsInteger(1);
    System.out.println("intValueAt1 = " + intValueAt1); // intValueAt1 = 4

    //Prints the json string
    System.out.println("toJsonString = " + jsonList.toJsonString()); // toJsonString = [1,4,0,1]

Since:

12.0.4
