16. Guillemets From Wikipedia, the free encyclopedia (Redirected from Guillemet)Guillemet Guillemets (pronounced / ˈɡɪ ləm ɛ t/, or / ɡ i ː ə ˈ me ɪ / after French [ ɡ ij(ə)m ɛ ]), also called angle quotes, are line segments, pointed as if arrows (« or »), sometimes forming a complementary set of punctuation marks used as a form of quotation mark. The symbol at either end – double « and » or single ‹ and › – is a guillemet. They are used in a number of languages to indicate speech. They are also used as symbols for rewind and fast forward./ ˈɡɪ ləm ɛ t// ɡ i ː ə ˈ me ɪ / [ ɡ ij(ə)m ɛ ]angle quotesquotation markrewindfast forward Etymology The word is a diminutive of the French name Guillaume (whose equivalent in English is William), after the French printer and punchcutter Guillaume le Bé (1525–1598). [1][2] Some languages derive their word for guillemets analogously; for example, the Irish term is Liamóg, from Liam 'William' and a diminutive suffix.diminutiveGuillaume le Bé [1][2]Irish 16

17. Guillemot From Wikipedia, the free encyclopedia Jump to: navigation, search For other uses, see Guillemot (disambiguation).navigationsearchGuillemot (disambiguation) Guillemot is the common name for several species of seabird in the order Charadriiformes, and the auk family, comprising two genera: Uria and Cepphus. This word of French origin apparently derives from a form of the name William, cf. the Welsh: Gwillim or the French: Guillaume. [1]common nameseabirdCharadriiformesauk UriaCepphusWilliamWelsh French [1] The Uria are known as murres in North America and, together with the Razorbill, Dovekie and the extinct Great Auk, make up the tribe Alcini. They have distinctly white bellies, thicker, longer bills than Cepphus and form very dense colonies on cliffs during the reproductive season.RazorbillDovekieextinctGreat Auktribe The three species of Cepphus - for which the term "guillemot" is generally reserved in North America - form a tribe of their own: Cepphini. They are smaller than the Uria species, have black bellies, rounder heads and bright red feet. 17

30. 30 15.4.2 A Larger Sequence Diagram Example Let this code be given: public abstract class Food { private String brand; private String productName; private String units; … public void setBrand(String brandIn) { brand = brandIn; } public String getBrand() { return brand; } …

31. 31 public void setBrandToThisBrand(Food anotherFood) { String tempBrand = anotherFood.getBrand(); setBrand(tempBrand); } … public abstract double getUnitCost(); }

32. 32 public class PackagedFood extends Food { private double size; private double itemCost; … public void setSize(double sizeIn) { size = sizeIn; } public double getSize() { return size; } … public double getUnitCost() { return itemCost / size; }

33. 33 Suppose the following is done in a calling program: PackagedFood myfood = new PackagedFood(…); PackagedFood yourfood = new PackagedFood(…); …

34. 34 Suppose this call is then made: myfood.setBrandToThisBrand(yourfood); The corresponding sequence diagram is shown on the next overhead.
