LoggedFormat
public class LoggedFormat extends Format (Code)
Wraps a Format object in order to either parse fully a string, or log a warning. This class provides a LoggedFormat.parse method which performs the following tasks:

  • Checks if the string was fully parsed and log a warning if it was not. This is different than the default LoggedFormat.parseObject(String) behavior which check only if the begining of the string was parsed and ignore any remaining characters.
  • Ensures that the parsed object is of some specific class specified at construction time.
  • If the string can't be fully parsed or is not of the expected class, logs a warning.

Constructor Detail
LoggedFormat
protected LoggedFormat(Format format, Class type)(Code)
Creates a new format wrapping the specified one.
Parameters:
  format - The format to use for parsing and formatting.
Parameters:
  type - The expected type of parsed values.




Method Detail
format
public StringBuffer format(Object value, StringBuffer toAppendTo, FieldPosition position)(Code)
Formats the specified object. This method delegates the work to the specified at construction time.
Parameters:
  value - The object to format.
Parameters:
  toAppendTo - The buffer where the text is to be appended.
Parameters:
  position - Identifies a field in the formatted text. The string buffer passed in with formatted text appended.



formatToCharacterIterator
public AttributedCharacterIterator formatToCharacterIterator(Object value)(Code)
Formats the specified object. This method delegates the work to the specified at construction time.
Parameters:
  value - The object to format. The character iterator describing the formatted value.



getInstance
public static LoggedFormat getInstance(Format format, Class type)(Code)
Creates a new format wrapping the specified one.
Parameters:
  format - The format to use for parsing and formatting.
Parameters:
  type - The expected type of parsed values.



getWarningLocale
protected Locale getWarningLocale()(Code)
Returns the locale to use for formatting warnings. The default implementation returns the .



logWarning
protected void logWarning(LogRecord warning)(Code)
Logs a warning. This method is invoked automatically by the LoggedFormat.parse parse method when a text can't be fully parsed. The default implementation logs the warning to the logger specified by the last call to the LoggedFormat.setLogger setLogger method. Subclasses may override this method if they want to change the log record before the logging.
Parameters:
  warning - The warning to log.



parse
public Object parse(String text)(Code)
Parses the specified string. If the string can't be parsed, then this method returns null . If it can be parsed at least partially and is of the kind specified at construction time, then it is returned. If the string has not been fully parsed, then a is prepared and logged.
Parameters:
  text - The text to parse, or null . The parsed object, or null if text was null or can't be parsed.



parseObject
public Object parseObject(String text) throws ParseException(Code)
Parses text from a string to produce an object. This method delegates the work to the specified at construction time. This method to not perform any logging.
Parameters:
  text - The text to parse. An object parsed from the string.
throws:
  ParseException - if parsing failed.



parseObject
public Object parseObject(String text, ParsePosition position)(Code)
Parses text from a string to produce an object. This method delegates the work to the specified at construction time. This method to not perform any logging.
Parameters:
  text - The text to parse.
Parameters:
  position - Index and error index information. An object parsed from the string, or null in case of error.



setCaller
public void setCaller(Class caller, String method)(Code)
Sets the and for the warnings eventually emitted by the LoggedFormat.parse method.
Parameters:
  caller - The class to declare as the warning emitter, or null if none.
Parameters:
  method - The method to declare as the warning emitter, or null if none.



setLogger
public void setLogger(String logger)(Code)
Sets the logger where to send the warnings eventually emitted by the LoggedFormat.parse method.
Parameters:
  logger - The logger where to log warnings, or null if none.



toString
public String toString()(Code)
Returns a string representation for debugging purpose.
