public class SavableClassUtil
extends Object

SavableClassUtil contains various utilities to handle Savable classes. The methods are general enough to not be specific to any particular implementation. Currently it will remap any classes from old paths to new paths so that old J3O models can still be loaded.

                                throws IOException

Throws:

IOException

getSavableVersion

public static int getSavableVersion(Class<? extends Savable> clazz)
                             throws IOException

Throws:

IOException

getSavedSavableVersion

public static int getSavedSavableVersion(Object savable,
 Class<? extends Savable> desiredClass,

fromName

public static Savable fromName(String className)
                        throws ClassNotFoundException,
IllegalAccessException,
InstantiationException,
InvocationTargetException

fromName creates a new Savable from the provided class name. First registered modules are checked to handle special cases, if the modules do not handle the class name, the class is instantiated directly.

Parameters:

className - the class name to create.

Returns:

the Savable instance of the class.

Throws:

InstantiationException - thrown if the class does not have an empty constructor.

IllegalAccessException - thrown if the class is not accessible.

InvocationTargetException - if the underlying constructor throws an exception

ClassNotFoundException - thrown if the class name is not in the classpath.
