Miscellaneous Helper Classes

Abstract

Any class library contains a motley assemblage of unheralded classes and interfaces that don’t submit readily to categorization. After careful consideration, class library designers gather up these recalcitrant classes and sweep them into one or more “utility” packages. Just as a utility tool belt carries a menagerie of tools that fulfill disparate purposes, a utility package holds an array of classes you can use to fill in the gaps left behind by the rest of the library. This chapter examines the utility packages that JFace offers.
