All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class BooleanFormat
extends java.text.Format

Default implementation of boolean format

It supports pattern configurable text representation for true and false. One has to pass following text to the constructor: "value-for-true;value-for-false".

null

format

public java.lang.StringBuffer format(java.lang.Object obj,
                                     java.lang.StringBuffer toAppendTo,
                                     java.text.FieldPosition pos)

format Boolean into predefined strings, one for true other for false.

One can change the default "true" and "false" by instantiating the object with proper pattern text. See above documentation.

format in class java.text.Format

Parameters:

obj - has to be java.lang.Boolean

toAppendTo - to append the string representation of obj

pos - is irrelevant in this method

Returns:

updated toAppendTo
