Interface DateParser

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.

Since:

3.2

Method Detail

parse

Date parse(String source)
    throws ParseException

Equivalent to DateFormat.parse(String). See DateFormat.parse(String) for more information.

Parameters:

source - A String 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

Date parse(String source,
           ParsePosition pos)

Equivalent to DateFormat.parse(String, ParsePosition). See DateFormat.parse(String, ParsePosition) for more information.

Parameters:

source - A String, part of which should be parsed.

pos - A ParsePosition 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

boolean parse(String source,
              ParsePosition pos,
              Calendar calendar)

Parse 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

getPattern

String getPattern()

Get the pattern used by this parser.

Returns:

the pattern, SimpleDateFormat compatible

getTimeZone

TimeZone getTimeZone()

Get the time zone used by this parser.

The default TimeZone used to create a Date when the TimeZone is not specified by the format pattern.

Returns:

the time zone

getLocale

Locale getLocale()

Get the locale used by this parser.

Returns:

the locale

parseObject

Object parseObject(String source)
            throws ParseException

Parses text from a string to produce a Date.

Parameters:

source - A String whose beginning should be parsed.

Returns:

a java.util.Date object

Throws:

ParseException - if the beginning of the specified string cannot be parsed.

See Also:

Format.parseObject(String)

parseObject

Object parseObject(String source,
                   ParsePosition pos)

Parse a date/time string according to the given parse position.

Parameters:

source - A String whose beginning should be parsed.

pos - the parse position

Returns:

a java.util.Date object
