- All Known Implementing Classes:
FastDateFormat
,FastDateParser
public interface DateParser
DateParser is the "missing" interface for the parsing methods of
DateFormat
. You can obtain an object implementing this
interface by using one of the FastDateFormat factory methods.
Warning: Since binary compatible methods may be added to this interface in any release, developers are not expected to implement this interface.

- 3.2

Method Details
-
getLocale
Gets the locale used by this parser.- Returns:
- the locale
-
getPattern
Gets the pattern used by this parser.- Returns:
- the pattern,
SimpleDateFormat
compatible
-
getTimeZone
Gets the time zone used by this parser.The default
TimeZone
used to create aDate
when theTimeZone
is not specified by the format pattern.- Returns:
- the time zone
-
parse
Equivalent to DateFormat.parse(String). SeeDateFormat.parse(String)
for more information.- Parameters:
source
- AString
whose beginning should be parsed.- Returns:
- A
Date
parsed from the string - Throws:
ParseException
- if the beginning of the specified string cannot be parsed.
-
parse
Equivalent to DateFormat.parse(String, ParsePosition). SeeDateFormat.parse(String, ParsePosition)
for more information.- Parameters:
source
- AString
, part of which should be parsed.pos
- AParsePosition
object with index and error index information as described above.- Returns:
- A
Date
parsed from the string. In case of error, returns null. - Throws:
NullPointerException
- if text or pos is null.
-
parse
Parses a formatted date string according to the format. Updates the Calendar with parsed fields. Upon success, the ParsePosition index is updated to indicate how much of the source text was consumed. Not all source text needs to be consumed. Upon parse failure, ParsePosition error index is updated to the offset of the source text which does not match the supplied format.- Parameters:
source
- The text to parse.pos
- On input, the position in the source to start parsing, on output, updated position.calendar
- The calendar into which to set parsed fields.- Returns:
- true, if source has been parsed (pos parsePosition is updated); otherwise false (and pos errorIndex is updated)
- Throws:
IllegalArgumentException
- when Calendar has been set to be not lenient, and a parsed field is out of range.- Since:
- 3.5
-
parseObject
Parses text from a string to produce a Date.- Parameters:
source
- AString
whose beginning should be parsed.- Returns:
- a
Date
object - Throws:
ParseException
- if the beginning of the specified string cannot be parsed.- See Also:
-
parseObject
Parses a date/time string according to the given parse position.
