/**
 * 

* The Builder interface is designed to designate a class as a builder * object in the Builder design pattern. Builders are capable of creating and * configuring objects or results that normally take multiple steps to construct * or are very complex to derive. *

* *

* The builder interface defines a single method, {@link #build()}, that * classes must implement. The result of this method should be the final * configured object or result after all building operations are performed. *

* *

* It is a recommended practice that the methods supplied to configure the * object or result being built return a reference to {@code this} so that * method calls can be chained together. *

* *

* Example Builder: *


 * class FontBuilder implements Builder<Font> {
 *     private Font font;
 *
 *     public FontBuilder(String fontName) {
 *         this.font = new Font(fontName, Font.PLAIN, 12);
 *     }
 *
 *     public FontBuilder bold() {
 *         this.font = this.font.deriveFont(Font.BOLD);
 *         return this; // Reference returned so calls can be chained
 *     }
 *
 *     public FontBuilder size(float pointSize) {
 *         this.font = this.font.deriveFont(pointSize);
 *         return this; // Reference returned so calls can be chained
 *     }
 *
 *     // Other Font construction methods
 *
 *     public Font build() {
 *         return this.font;
 *     }
 * }
 * 
* * Example Builder Usage: *

 * Font bold14ptSansSerifFont = new FontBuilder(Font.SANS_SERIF).bold()
 *                                                              .size(14.0f)
 *                                                              .build();
 * 
* * * @param the type of object that the builder will construct or compute. * @since 1.0 * */ public interface Builder { /** * Returns a reference to the object being constructed or result being * calculated by the builder. * * @return the object constructed or result calculated by the builder. */ T build(); }
