## ncsa.hdf.hdf5lib.callbacks
Interface Callbacks

All Known Subinterfaces:
  H5D_iterate_cb, H5L_iterate_cb, H5O_iterate_cb

    public interface Callbacks

All callback definitions must derive from this interface. Any derived interfaces must define a single public method named "callback". You are responsible for deregistering your callback (if necessary) in its `Object.finalize()` method. If native code attempts to call a callback which has been GC'd, you will likely crash the VM. If there is no method to deregister the callback (e.g. `atexit` in the C library), you must ensure that you always keep a live reference to the callback object.

A callback should generally never throw an exception, since it doesn't necessarily have an encompassing Java environment to catch it. Any exceptions thrown will be passed to the default callback exception handler.
