/**
 * Base class for all formats. This is an abstract base class which
 * specifies the protocol for classes which convert other objects or
 * values, such as numeric values and dates, and their string
 * representations. In some cases these representations may be
 * localized or contain localized characters or strings. For example,
 * a numeric formatter such as DecimalFormat may convert a numeric
 * value such as 12345 to the string "$12,345". It may also parse
 * the string back into a numeric value. A date and time formatter
 * like SimpleDateFormat may represent a specific date, encoded
 * numerically, as a string such as "Wednesday, February 26, 1997 AD".
 * 
 * Many of the concrete subclasses of Format employ the notion of
 * a pattern. A pattern is a string representation of the rules which
 * govern the interconversion between values and strings. For example,
 * a DecimalFormat object may be associated with the pattern
 * "$#,##0.00;($#,##0.00)", which is a common US English format for
 * currency values, yielding strings such as "$1,234.45" for 1234.45,
 * and "($987.65)" for 987.6543. The specific syntax of a pattern
 * is defined by each subclass.
 * 
 * Even though many subclasses use patterns, the notion of a pattern
 * is not inherent to Format classes in general, and is not part of
 * the explicit base class protocol.
 * 
 * Two complex formatting classes bear mentioning. These are
 * MessageFormat and ChoiceFormat. ChoiceFormat is a subclass of
 * NumberFormat which allows the user to format different number ranges
 * as strings. For instance, 0 may be represented as "no files", 1 as
 * "one file", and any number greater than 1 as "many files".
 * MessageFormat is a formatter which utilizes other Format objects to
 * format a string containing with multiple values. For instance,
 * A MessageFormat object might produce the string "There are no files
 * on the disk MyDisk on February 27, 1997." given the arguments 0,
 * "MyDisk", and the date value of 2/27/97. See the ChoiceFormat
 * and MessageFormat headers for further information.
 * 
 * If formatting is unsuccessful, a failing UErrorCode is returned when
 * the Format cannot format the type of object, otherwise if there is
 * something illformed about the the Unicode replacement character
 * 0xFFFD is returned.
 * 
 * If there is no match when parsing, a parse failure UErrorCode is
 * returned for methods which take no ParsePosition. For the method
 * that takes a ParsePosition, the index parameter is left unchanged.
 * 
 * User subclasses are not supported. While clients may write
 * subclasses, such code will not necessarily work and will not be
 * guaranteed to work stably from release to release.

/**
 * Parse a string to produce an object. This is a pure virtual
 * method which subclasses must implement. This method allows
 * polymorphic parsing of strings into Formattable objects.
 * 
 * Before calling, set parse_pos.index to the offset you want to
 * start parsing at in the source. After calling, parse_pos.index
 * is the end of the text you parsed. If error occurs, index is
 * unchanged.
 * 
 * When parsing, leading whitespace is discarded (with successful
 * parse), while trailing whitespace is left as is.
 * 
 * Example:
 * 
 * Parsing "_12_xy" (where _ represents a space) for a number,
 * with index == 0 will result in the number 12, with
 * parse_pos.index updated to 3 (just before the second space).
 * Parsing a second time will result in a failing UErrorCode since
 * "xy" is not a number, and leave index at 3.
 * 
 * Subclasses will typically supply specific parse methods that
 * return different types of values. Since methods can't overload
 * on return types, these will typically be named "parse", while
 * this polymorphic method will always be called parseObject. Any
 * parse method that does not take a parse_pos should set status
 * to an error value when no text in the required format is at the
 * start position.
 *
 * @param source The string to be parsed into an object.
 * @param result Formattable to be set to the parse result.
 * If parse fails, return contents are undefined.
 * @param parse_pos The position to start parsing at. Upon return
 * this param is set to the position after the
 * last character successfully parsed. If the
 * source is not parsed successfully, this param
 * will remain unchanged.
