public Class FastDateFormat

extends DateFormat
Class Inheritance
Imports
java.text.DateFormat, .FieldPosition, .ParsePosition, java.util.Date
Fast date formatter that caches recently formatted date information and uses it to avoid too-frequent calls to the underlying formatter.

Note

breaks fieldPosition param of format(Date, StringBuffer, FieldPosition). If you care about the field position, call the underlying DateFormat directly.

public StringBuffer format(Date date, StringBuffer toAppendTo, FieldPosition fieldPosition)

Implements abstract java.text.DateFormat.format.

Note

breaks functionality of fieldPosition param. Also: there's a bug in SimpleDateFormat with "S" and "SS", use "SSS" instead if you want a msec field.

public Date parse(String text, ParsePosition pos)

Implements abstract java.text.DateFormat.parse.

Doc from java.text.DateFormat.parse.

Parse a date/time string according to the given parse position. For example, if this has the pattern "M/d/yy h:m a, z", then a time text "07/10/96 4:5 PM, PDT" will be parsed into a Date that is equivalent to Date(837039900000L).

By default, parsing is lenient: If the input is not in the form used by this object's format method but can still be parsed as a date, then the parse succeeds. Clients may insist on strict adherence to the format by calling setLenient(false).

This parsing operation uses the calendar to produce a Date. As a result, the calendar's date-time fields and the TimeZone value may have been overwritten, depending on subclass implementations. Any TimeZone value that has previously been set by a call to setTimeZone may need to be restored for further operations.
