FastDateParser

public FastDateParser(String pattern,
                      TimeZone timeZone,
                      Locale locale)

Constructs a new FastDateParser.

Use FastDateFormat.getInstance(String, TimeZone, Locale) or another variation of the factory methods of FastDateFormat to get a cached FastDateParser instance.

参数:

pattern - non-null SimpleDateFormat compatible pattern

timeZone - non-null time zone to use

locale - non-null locale

FastDateParser

public FastDateParser(String pattern,
                      TimeZone timeZone,
                      Locale locale,
                      Date centuryStart)

Constructs a new FastDateParser.

参数:

pattern - non-null SimpleDateFormat compatible pattern

timeZone - non-null time zone to use

locale - non-null locale

centuryStart - The start of the century for 2 digit year parsing

方法详细资料

parse

public Date parse(String source)
           throws DateException

从接口复制的说明: DateParser

将日期字符串解析并转换为 Date 对象
等价于 DateFormat.parse(String)

指定者:

parse 在接口中 DateParser

参数:

source - 被解析的日期字符串

返回:

Date对象

抛出:

DateException - 转换异常，被转换的字符串格式错误。

parse

public Date parse(String source,
                  ParsePosition pos)

从接口复制的说明: PositionDateParser

将日期字符串解析并转换为 Date 对象
等价于 DateFormat.parse(String, ParsePosition)

指定者:

parse 在接口中 PositionDateParser

参数:

source - 日期字符串

pos - ParsePosition

返回:

Date

parse

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

从接口复制的说明: PositionDateParser

根据给定格式更新Calendar 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.

指定者:

parse 在接口中 PositionDateParser

参数:

source - 被转换的日期字符串

pos - 定义开始转换的位置，转换结束后更新转换到的位置

calendar - The calendar into which to set parsed fields.

返回:

true, if source has been parsed (pos parsePosition is updated); otherwise false (and pos errorIndex is updated)
