Examples with JsonNull com.google.gson.JsonNull used on opensource projects

Example 1 with JsonNull

use of com.google.gson.JsonNull in project st-js by st-js.

the class JSArrayAdapter method serialize.

/**
 * {@inheritDoc}
 */
@Override
public JsonElement serialize(Array<?> array, Type type, JsonSerializationContext ctx) {
    if (array == null) {
        return new JsonNull();
    }
    JsonArray js = new JsonArray();
    // validate that we have a packed array (no unset elements) and that we do not
    // have any non-array indices. JSON supports none of these features, and toList()
    // detects them and rejects them too.
    List<?> list = array.toList();
    return ctx.serialize(list);
}

Example 2 with JsonNull

use of com.google.gson.JsonNull in project RxReddit by damien5314.

    JsonArray array = json.getAsJsonArray();
    // Extract text element
    JsonElement textElement = array.get(0);
    String text = textElement instanceof JsonNull ? null : textElement.getAsString();

    String username = array.get(1).getAsString();
    return new ModReport(text, username);
