Builders are capable of creating and * configuring objects or results that normally take multiple steps to construct * or are very complex to derive. * </p> * * <p> * 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. * </p> * * <p> * 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. * </p> * * <p> * Example Builder: * <pre><code> * 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; * } * } * </code></pre> * * Example Builder Usage: * <pre><code> * Font bold14ptSansSerifFont = new FontBuilder(Font.SANS_SERIF).bold() * .size(14.0f) * .build(); * </code></pre> * * * @param <T> the type of object that the builder will construct or compute. * * @since 3.0 */ @FunctionalInterface public interface Builder<T> { /** * 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(); }
