Package acm.util

This package includes several classes that are common to the ACM package suite.

See: Description

Class Summary

Class	Description
Animator	This class extends Thread to provide several features that make it easier to build animations.
FileChooserFilter	This class extends javax.swing.filechooser.FileFilter and exists primarily to avoid the ambiguity that arises because there is also a FileFilter class in java.io.
JTFTools	This class provides a collection of static utility methods that are used elsewhere in the ACM packages.
MediaTools	This class implements a standard mechanism for loading images, sounds, and data files from the resources associated with a jar file.
OptionTable	This class implements a simple tool for parsing key/value pairs from a string.
Platform	This class contains methods to support platform-specific code.
RandomGenerator	This class implements a simple random number generator that allows clients to generate pseudorandom integers, doubles, booleans, and colors.
SwingTimer	This class is equivalent to javax.swing.Timer and exists only to avoid the ambiguity that arises because there is also a Timer class in java.util.

Exception Summary

Exception	Description
CancelledException	This class allows a dialog to signal clients that it has been cancelled.
ErrorException	This class allows errors to be reported in a consistent way.

Package acm.util Description

This package includes several classes that are common to the ACM package suite. Novice users of the package will, in general, not need to use most of these classes. The following list provides a brief description of each of the acm.util classes, starting with the classes that are most likely to be of use:

RandomGenerator

This class extends the Random and offers a few useful simplifications for working with pseudorandom values.

MediaTools

This class includes several static methods that support the use of images and sounds.

acm.util.SoundClip

This class represents a sound that can be played through the computer.

acm.util.MovieClip

This class represents a QuickTime movie that can be played on the screen.

ErrorException

This class is used to signal errors anywhere in the ACM Java Library collection. The primary advantage of ErrorException is that it is defined as a RuntimeException subclass and therefore does not need to be caught or declared in a throws clause.

CancelledException

This class allows a dialog to signal clients that it has been cancelled.

CancelledException

This class allows a dialog to signal clients that it has been cancelled.

Platform

This class contains several methods that support platform-specific code.

SwingTimer

This class is equivalent to Timer and exists only to avoid the ambiguity that arises because there is also a Timer class in java.util.

FileChooserFilter

This class provides a simple implementation of the abstract FileFilter class.

OptionTable

This class implements a simple tool for parsing key/value pairs from a string. Its primary use is for parsing the options used in the TableLayout class.

JTFTools

This class provides a collection of static utility methods that are used elsewhere in the ACM packages.
