| DecimalFormatFilter | | public class DecimalFormatFilter extends NumberFormatFilter (Code) | | A filter that formats the numeric value from a data source to a string representation
using the decimal number system as base.
This filter will format java.lang.Number objects using a java.text.DecimalFormat to
create the string representation for the date obtained from the datasource.
If the object read from the datasource is no date, the NullValue defined by
setNullValue(Object) is returned.

the localized pattern string of the format-object. |
| getValue | | public Object getValue(ExpressionRuntime runtime)(Code) | | 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.
Parameters:
runtime - the expression runtime that is used to evaluate formulas and expressions when computing the value ofthis filter. The formatted value. |
| isKeepState | | public boolean isKeepState()(Code) | | Defines, whether the filter should keep its state, if a locale
change is detected. This will effectivly disable the locale update.
true, if the locale should not update the DateSymbols, false otherwise. |
| setDecimalFormat | | public void setDecimalFormat(DecimalFormat format)(Code) | | Sets the format for the filter.
Parameters:
format - the format.

ClassCastException is thrown
Parameters:
format - the format.

throws:
ClassCastException - if the format is no decimal format |
| setKeepState | | public void setKeepState(boolean keepState)(Code) | | Defines, whether the filter should keep its state, if a locale
change is detected. This will effectivly disable the locale update.
Parameters:
keepState - set to true, if the locale should not update the DateSymbols, false otherwise. |
| setLocalizedFormatString | | public void setLocalizedFormatString(String format)(Code) | | Applies a localised format string to the internal DecimalFormat
instance.
