How to use

getPackageName

method

in

java.lang.Class

  /**
   * Specifies how the Java methods in the given interface should be mapped to Python methods or attributes.
   * There is two main interfacing modes supported by default: if this method returns {@link Interfacing#GEOAPI},
   * then the mapping between Java and Python uses the following rules:
   *
   * <ul>
   *   <li>For any Java method, the name of the corresponding Python attribute is given
   *       by the {@link org.opengis.annotation.UML} annotation associated to the method.
   *       If a method has no such annotation, then its name is used as a fallback.</li>
   *   <li>GeoAPI-specific property types are supported ({@link org.opengis.util.CodeList}
   *       and {@link InternationalString}) in addition of some Java standard types like
   *       {@link Enum} and {@link java.util.Collection}.</li>
   * </ul>
   *
   * If this method returns {@link Interfacing#DEFAULT},
   * then the Python-Java mapping is delegated to the underlying JPY library.
   * If this method returns another value, then the behavior is defined by
   * {@link Interfacing#toJava(PyObject, Class)}.
   *
   * @param  type  the Java type for which to determine the interfacing mode.
   * @return a specification of how to interface Java methods to Python.
