Names of design patterns appear in small capitals: e.g., ADAPTER. Page numbers in bold indicate the definition of a term. Numbers in italics indicate a diagram for the term. Letters after a diagram's page number indicate the kind of diagram: a "c" denotes a class diagram, an "i" denotes an interaction diagram, and an "o" denotes an object diagram. For example, 88co means that a class and object diagram appears on page 88.
