<div class="block">Superclass for all generated ProcAddressTables.
A ProcAddressTable is a cache of pointers to the dynamically-linkable C
functions this autogenerated Java binding has exposed. Some
libraries such as OpenGL, OpenAL and others define function pointer
signatures rather than statically linkable entry points for the
purposes of being able to query at run-time whether a particular
extension is available. This table acts as a cache of these
function pointers. Each function pointer is typically looked up at
run-time by a platform-dependent mechanism such as dlsym(),
wgl/glXGetProcAddress(), or alGetProcAddress(). If the field containing the function
pointer is 0, the function is considered to be unavailable and can
not be called.</div>
