Method Detail

getNumberFormat

protected java.text.NumberFormat getNumberFormat()

Returns a NumberFormat instance to use for formatting and parsing in this AbstractNumberConverter.

Returns:

a NumberFormat.

numberFromString

public java.lang.Number numberFromString(java.lang.String string,
                                         ConverterContext context)
