Utility Classes – things you may find useful

To defer code duplication a lot of functionality is lifted out to utility

classes. DateUtil is such a class. DateRange is another. Here is

a list over some of the classes available to the user of the MiG

Calendar Component.

• DateUtil. Static methods for different kinds of date

manipulation. Calendar rounding to boundaries (e.g. day or

hour), flexible and fast duration string formatting and week bases

helper functions are some of the things this class can do.

• GfxUtil. Contains a lot of geometry calculation methods, mostly

based on Rectangle or Rectangle2D. Color manipulation,

lots of string drawing methods, image and texture blending and

improved image loading are examples of what this class provides.

• DateRange. This is a class, or rather class hierarchy, used

extensively throughout the MiG Calendar component, but it has

uses outside communicating with the component. It encapsulates a

start and end time and a lot of operations on that period. Iterating

over it at specified multiples of a boundary is one example. It exists

both as a truly immutable and a mutable version as well as it

implement both a mutable and immutable interfaces.

• Misc. graphics classes. UIColor, SlicedImage,

XtdTexturePaint and ArrowButton are some of the

usable classes in the util.gfx package.

• Base64 encoder/decoder. The fastest Java bases base64 encoder

and decoder is included. It is developed by MiG InfoCom AB and

Open Sourced. It can be downloaded from

http://migbase64.sourceforge.net where there also are some

performance comparison charts.

• IO. The util.io.IOUtil class adds support for aggregating

XML delegates (java.beans.PersistenceDelegate)

used for saving and loading unsupported object types to XML with

the standard 1.4+ XMLEncoder and XMLDecoder. If you want

to add a object type of your own and that type doesn't follow the
