public DecimalFormatFilter() 
{
    setFormatter(new DecimalFormat());
}

DefaultConstructor, this object is initialized using a DecimalFormat with the default pattern for this locale.

 public DecimalFormat getDecimalFormat() 
{
    return (DecimalFormat) getFormatter();
}

Returns the format for the filter. The DecimalFormatParser has only DecimalFormat objects assigned.

 public String getFormatString() 
{
    return getDecimalFormat().toPattern();
}

Synthesizes a pattern string that represents the current state of this Format object.

 public FormatSpecification getFormatString(ExpressionRuntime runtime,
    Element element,
    FormatSpecification formatSpecification) 
{
    if (formatSpecification == null)
    {
      formatSpecification = new FormatSpecification();
    }
    formatSpecification.redefine(FormatSpecification.TYPE_DECIMAL_FORMAT, getFormatString());
    return formatSpecification;
}

 public String getLocalizedFormatString() 
{
    return getDecimalFormat().toLocalizedPattern();
}

Synthesizes a localized pattern string that represents the current state of this Format object.

 public Object getValue(ExpressionRuntime runtime,
    Element element) 
{
    if (keepState == false && runtime != null)
    {
      final Locale locale = runtime.getResourceBundleFactory().getLocale();
      if (locale != null && locale.equals(lastLocale) == false)
      {
        lastLocale = locale;
        getDecimalFormat().setDecimalFormatSymbols(new DecimalFormatSymbols(locale));
        invalidateCache();
      }
    }
    return super.getValue(runtime, element);
}

Returns the formatted string. The value is read using the data source given and formated using the formatter of this object. The formating is guaranteed to completly form the object to an string or to return the defined NullValue.

If format, datasource or object are null, the NullValue is returned.

 public boolean isKeepState() 
{
    return keepState;
}

Defines, whether the filter should keep its state, if a locale change is detected. This will effectivly disable the locale update.

 public  void setDecimalFormat(DecimalFormat format) 
{
    setFormatter(format);
}

Sets the format for the filter.

 public  void setFormatString(String format) 
{
    getDecimalFormat().applyPattern(format);
    invalidateCache();
}

Applies a format string to the internal DecimalFormat instance.

 public  void setFormatter(Format format) 
{
    final DecimalFormat dfmt = (DecimalFormat) format;
    super.setFormatter(dfmt);
}

Sets the format for the filter. If the given format is no Decimal format, a ClassCastException is thrown

 public  void setKeepState(boolean keepState) 
{
    this.keepState = keepState;
}

Defines, whether the filter should keep its state, if a locale change is detected. This will effectivly disable the locale update.

 public  void setLocalizedFormatString(String format) 
{
    getDecimalFormat().applyLocalizedPattern(format);
    invalidateCache();
}

Applies a localised format string to the internal DecimalFormat instance.
