Method Detail

initClassLoader

public static java.lang.ClassLoader initClassLoader(long classVersion)
                                             throws java.lang.Exception

If PdxPrms.initClassLoader is true, then randomly choose a versioned class path and create and install a class loader for it on this thread.

Returns:

The installed class loader (which includes a versioned class path) or null if this call did not install a new class loader.

Throws:

java.lang.Exception

getVersionedInstance

public static java.lang.Object getVersionedInstance(java.lang.String className,
                                                    java.lang.Object[] args)
                                             throws java.lang.Exception

Use reflection to create a new instance of a versioned class whose name is specified by className. Since versioned classes are compled outside outside the /tests directory, code within /tests cannot directly reference versioned classes, however the versioned class should be available at runtime if the test has installed the correct class loader.

Parameters:

className - The name of the versioned class to create.

Returns:

A new instance of className.

Throws:

java.lang.Exception
