setHook

public static void setHook(JavaLayerHook hook0)

Sets the system-wide JavaLayer hook.

getHook

public static JavaLayerHook getHook()

getResourceAsStream

public static java.io.InputStream getResourceAsStream(java.lang.String name)

Retrieves an InputStream for a named resource.

Parameters:

name - The name of the resource. This must be a simple name, and not a qualified package name.
