Example 2 with Resources

use of org.apache.pivot.util.Resources in project pivot by apache.

/**

 * base type is also used as the base name of the resource bundle.
 *
 * @param baseType The base type.
 * @param resourceName The name of the BXML resource.
 * @param localize If <tt>true</tt>, the deserialized resource will be
 * localized using the resource bundle specified by the base type.
 * Otherwise, it will not be localized, and any use of the resource
 * resolution operator will result in a serialization exception.
 * @return the top-level deserialized object.
 * @throws IllegalArgumentException for <tt>null</tt> type or resource name or if
 * the resource could not be found.
 * @throws IOException for any error reading the BXML resource.
 * @throws SerializationException for any other errors encountered deserializing the resource.
 * @see #readObject(URL, Resources)
