Method Summary
protected  StringformatNumber(Object value, String defaultFormat)
     Formats a number (Integer, BigDecimal...) into a string.
public  intgetRoundingMode()
     Returns the rounding mode.
public  voidsetRoundingMode(int mode)
     Sets the rounding mode. Note: You cannot change the rounding mode unless you are using Java 6 or later.
Parameters:
  mode - the rounding mode.
public  voidsetRoundingMode(String name)
     Sets the rounding mode by the name. Note: You cannot change the rounding mode unless you are using Java 6 or later.
Parameters:
  name - the rounding mode's name.
protected  Object[]toNumberOnly(String val)
     Filters out non digit characters, such comma and whitespace, from the specified value. It is designed to let user enter data in more free style. They may or may not enter data in the specified format. a two element array.



Method Detail
formatNumber
protected String formatNumber(Object value, String defaultFormat)(Code)
Formats a number (Integer, BigDecimal...) into a string. If null, an empty string is returned.

A utility to assist the handling of numeric data.
See Also:   NumberInputElement.toNumberOnly
Parameters:
  defaultFormat - used if NumberInputElement.getFormat returns null.If defaultFormat and NumberInputElement.getFormat are both null,the system's default format is used.




getRoundingMode
public int getRoundingMode()(Code)
Returns the rounding mode.

Default: BigDecimal.ROUND_HALF_EVEN .




setRoundingMode
public void setRoundingMode(int mode)(Code)
Sets the rounding mode. Note: You cannot change the rounding mode unless you are using Java 6 or later.
Parameters:
  mode - the rounding mode. Allowed value:BigDecimal.ROUND_CEILING, BigDecimal.ROUND_DOWN,BigDecimal.ROUND_FLOOR, BigDecimal.ROUND_HALF_DOWN,BigDecimal.ROUND_HALF_UP, BigDecimal.ROUND_HALF_EVEN,BigDecimal.ROUND_UNNECESSARY and BigDecimal.ROUND_UP
exception:
  UnsupportedOperationException - if Java 5 or below



setRoundingMode
public void setRoundingMode(String name)(Code)
Sets the rounding mode by the name. Note: You cannot change the rounding mode unless you are using Java 6 or later.
Parameters:
  name - the rounding mode's name. Allowed value:
CEILING
Rounding mode to round towards positive infinity.
DOWN
Rounding mode to round towards zero.
FLOOR
Rounding mode to round towards negative infinity.
HALF_DOWN
Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down.
HALF_EVEN
Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor.
HALF_UP
Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round up.
UNNECESSARY
Rounding mode to assert that the requested operation has an exact result, hence no rounding is necessary.
UP
Rounding mode to round away from zero.

exception:
  UnsupportedOperationException - if Java 5 or below
See Also:   RoundingModes



toNumberOnly
protected Object[] toNumberOnly(String val)(Code)
Filters out non digit characters, such comma and whitespace, from the specified value. It is designed to let user enter data in more free style. They may or may not enter data in the specified format. a two element array. The first element is the string toparse with, say, Double.parseDouble. The second element isan integer to indicate how many digits the result shall be scaled.For example, if the second element is 2. Then, the result shall bedivided with 10 ^ 2.
