the class ProxyDocument method getField.

/**
 * note that the returned Field may not be in this Document
 * directly, but may refer to a field in a struct contained in it,
 * in which case the returned Field is only useful for obtaining
 * the field type; it can't be used for get() and set().

public Field getField(String fieldName) {
    if (fieldMap != null && fieldMap.containsKey(fieldName)) {
        fieldName = fieldMap.get(fieldName);
    }
    FieldPath path = getFieldPath(fieldName);
    Field ret = path.get(path.size() - 1).getFieldRef();
    checkAccess(ret);
    return ret;
}
