Class ComposedFormat

java.lang.Object
  java.text.Format
      com.gridsystems.utils.text.ComposedFormat

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class ComposedFormat
extends java.text.Format

Format implementation that performs a "chained" format over the passed object.

The internal formatters specified at construction time are sequentially invoked to perform the formatting in the same order they are in the array.

For example, an following code:

Format f = new ComposedFormat(
new DecimalFormat("#,##0.00"),
new MessageFormat("<span style='color:red'>{0}</span>"); );

System.out.println(f.format(new Integer(3500)));

will produce the next output:

<span style='color:red'>3.500,00</span>
