public final class BtcAutoFormat extends BtcFormat
This class, a concrete extension of BtcFormat
, is distinguished by its
accommodation of multiple denominational units as follows:
When formatting Bitcoin monetary values, an instance of this class automatically adjusts the denominational units in which it represents a given value so as to minimize the number of consecutive zeros in the number that is displayed, and includes either a currency code or symbol in the formatted value to indicate which denomination was chosen.
When parsing String
representations of Bitcoin monetary values, instances of
this class automatically recognize units indicators consisting of currency codes and
symbols, including including those containing currency or metric prefixes such as
"ยข"
or "c"
to indicate hundredths, and interpret each number being
parsed in accordance with the recognized denominational units.
A more detailed explanation, including examples, is in the documentation for the BtcFormat
class, and further information beyond that is in the documentation for the Format
class, from which this class descends.

As a side-effect, this sets the units indicators of the underlying NumberFormat object. Only invoke this from a synchronized method, and be sure to put the DecimalFormatSymbols back to its proper state, otherwise immutability, equals() and hashCode() fail.
