Interface Summary

Interface	Description
Filter	An interface for objects that filter other objects
ModelParser	ModelParser is an interface that should be extended by application specified model parsers.
ModelWriter	ModelWriter is an interface that should be extended by application specified model writers to write out data structures to an output stream.
PropertyContainer	An object that can be annotated with arbitrary objects whose keys are strings.
SemanticObjectContainer	An object which is annotated with a single "semantic object" which is its semantic equivalent in an application.
UserObjectContainer	An object which is annotated with a single "user object" which is its semantic equivalent in an application.

Class Summary

Class	Description
ArrayIterator	An iterator over a given array.
BasicPropertyContainer	An object that can be annotated with arbitrary objects whose keys are strings.
CompoundIterator	An iterator over two iterators.
FilteredArrayIterator	An iterator over an array, in which elements are filtered by some function.
FilteredIterator	An iterator that takes another iterator, and applies a filter to each element that it gets.
IteratorAdapter	An iterator that implements the Iterator, intended for subclassing so that you don't have to provide the remove() method all the time....
IteratorIterator	An iterator that takes an iterator over objects that themselves produce iterators, and which iterators over the elements in the sub-iterators.
IteratorUtilities	A collection of utilities dealing with iterators.
LoggableOp	This is an abstract base class for objects that need to log error or warning messages.
NullArrayIterator	An iterator over a given array which may contain nulls.
NullIterator	An iterator over nothing.
PropertyChangeMulticaster	A list of PropertyChangeListeners.

Package diva.util Description

A package of utility classes. These classes may be used by any package in Diva. The classes are grouped into:

• Property support. A small set of classes design to "cache hash-tables" for more efficient access.
• Miscellenaous clases. Typically convenience classes and classes that "should" be in the JDK.
