Examples of javolution.text.TextFormat

javolution.text.TextFormat

nes the default format for complex numbers (Cartesian form) protected static TextFormat TEXT_FORMAT = new TextFormat (Complex.class) { ... } public static Complex valueOf(CharSequence csq) { return TEXT_FORMAT.parse(csq); } }[/code] The format associated to any given class/object can be dynamically retrieved. [code] public abstract class Number implements ValueType { public final Text toText() { return TextFormat.getInstance(this.getClass()).format(this); } public final String toString() { return TextFormat.getInstance(this.getClass()).formatToString(this); } }[/code] The default format can be locally overriden. [code] LocalContext.enter(); try { TextFormat polarFormat = new TextFormat(null) {...} // Unbound format. TextFormat.setInstance(Complex.class, polarFormat); // Local setting (no impact on others thread). System.out.println(complex); // Displays complex in polar coordinates. } finally { LocalContext.exit(); // Reverts to previous cartesian setting. }[/code]

For parsing/formatting of primitive types, the {@link TypeFormat}utility class is recommended.
