Method Detail

setClassLoader

public static void setClassLoader(java.lang.ClassLoader newClassLoader)

Parameters:

newClassLoader - The new class loader to use. This may be null in which case the system class loader will be used.

getClassLoader

public static java.lang.ClassLoader getClassLoader()

Returns the class loader which is used by the forName(String) method to load classes.

Returns:

The class loader used by forName(String) or null if the system class loader is used.
