Examples of com.google.gson.JsonArray

com.google.gson.JsonArray
A class representing an array type in Json. An array is a list of {@link JsonElement}s each of which can be of a different type. This is an ordered list, meaning that the order in which elements are added is preserved. @author Inderjeet Singh @author Joel Leitch

    JsonElement element = new JsonParser().parse(json);


    JsonObject objElem = (JsonObject) valueReader.get(element, "object");
    assertEquals(objElem.get("subkey").getAsString(), "subvalue");


    JsonArray arrayElem = (JsonArray) valueReader.get(element, "array");
    assertEquals(Arrays.asList(arrayElem.get(0).getAsString(), arrayElem.get(1).getAsString()),
        Arrays.asList("elem1", "elem2"));


    assertEquals(valueReader.get(element, "boolean"), true);
    assertEquals(((Number) valueReader.get(element, "number")).intValue(), 55);
    assertEquals(valueReader.get(element, "string"), "foo");
