java.lang.Object
   javolution.text.TextFormat

TextFormat
abstract public class TextFormat (Code)

This class represents the base format for text parsing and formatting; it supports CharSequence and javolution.text.Appendable interfaces for greater flexibility.

It is possible to retrieve the format for any class for which the format has been registered (typically during class initialization). For example:[code] public class Complex extends RealtimeObject { private static final TextFormat CARTESIAN = ...; static { // Sets default format to cartesian, users may change it later (e.g. polar). TextFormat.setInstance(Complex.class, CARTESIAN); } public Complex valueOf(CharSequence csq) { return TextFormat.getInstance(Complex.class).parse(csq); } public Text toText() { return TextFormat.getInstance(Complex.class).format(this); } }[/code]

For parsing/formatting of primitive types, the TypeFormat utility class is recommended.

Note: The format behavior may depend upon javolution.context.LocalContext local settings in which case concurrent threads may parse differently!

Inner Class :public static class Cursor extends ParsePosition


Constructor Summary
protected  TextFormat()
     Default constructor.

Method Summary
abstract public  Appendableformat(Object obj, Appendable dest)
     Formats the specified object into an Appendable
Parameters:
  obj - the object to format.
Parameters:
  dest - the appendable destination.
final public  Appendableformat(Object obj, TextBuilder dest)
     Formats the specified object into a TextBuilder (convenience method which does not raise IOException).
final public  Textformat(Object obj)
     Formats the specified object to a Text instance (convenience method).
Parameters:
  obj - the object being formated.
public static  TextFormatgetInstance(Class cls)
     Returns the text format for instances of specified type (class or interface).
abstract public  Objectparse(CharSequence csq, Cursor cursor)
     Parses a portion of the specified CharSequence from the specified position to produce an object.
final public  Objectparse(CharSequence csq)
     Parses a whole character sequence from the beginning to produce an object (convenience method).
public static  voidsetInstance(Class cls, TextFormat format)
     Associates the specified format to the specified type (class or interface).


Constructor Detail
TextFormat
protected TextFormat()(Code)
Default constructor.




Method Detail
format
abstract public Appendable format(Object obj, Appendable dest) throws IOException(Code)
Formats the specified object into an Appendable
Parameters:
  obj - the object to format.
Parameters:
  dest - the appendable destination. the specified Appendable.
throws:
  IOException - if an I/O exception occurs.



format
final public Appendable format(Object obj, TextBuilder dest)(Code)
Formats the specified object into a TextBuilder (convenience method which does not raise IOException).
Parameters:
  obj - the object to format.
Parameters:
  dest - the text builder destination. the specified text builder.



format
final public Text format(Object obj)(Code)
Formats the specified object to a Text instance (convenience method).
Parameters:
  obj - the object being formated. the text representing the specified object.



getInstance
public static TextFormat getInstance(Class cls)(Code)
Returns the text format for instances of specified type (class or interface). The following types are always recognized:
  • java.lang.Boolean
  • java.lang.Character
  • java.lang.Byte
  • java.lang.Short
  • java.lang.Integer
  • java.lang.Long
  • java.lang.Float
  • java.lang.Double
  • java.lang.Class
Users may register additional types using the TextFormat.setInstance TextFormat.setInstance(Class, TextFormat) static method. For example:[code] TextFormat fontFormat = new TextFormat() { public Appendable format(Font font, Appendable dest) throws IOException { return dest.append(font.getName()); } public Font parse(CharSequence csq, Cursor cursor) { CharSequence fontName = csq.subSequence(cursor.getIndex(), cursor.getEndIndex()); cursor.increment(fontName.length()); return Font.decode(fontName.toString()); } }); TextFormat.setInstance(Font.class, fontFormat); // Registers format for java.awt.Font [/code]
Parameters:
  cls - the class for which the default format is returned. the format for instances of the specified class or null if unkown.



parse
abstract public Object parse(CharSequence csq, Cursor cursor)(Code)
Parses a portion of the specified CharSequence from the specified position to produce an object. If parsing succeeds, then the index of the cursor argument is updated to the index after the last character used.
Parameters:
  csq - the CharSequence to parse.
Parameters:
  cursor - the cursor holding the current parsing index. the object parsed from the specified character sub-sequence.
throws:
  RuntimeException - if any problem occurs while parsing the specified character sequence (e.g. illegal syntax).



parse
final public Object parse(CharSequence csq)(Code)
Parses a whole character sequence from the beginning to produce an object (convenience method).
Parameters:
  csq - the whole character sequence to parse. the corresponding object.
throws:
  IllegalArgumentException - if the specified character sequence cannot be fully parsed.



setInstance
public static void setInstance(Class cls, TextFormat format)(Code)
Associates the specified format to the specified type (class or interface).
Parameters:
  cls - the class for which the default format is returned.
Parameters:
  format - the format for instances of the specified calss class.
