Example 1 with Style

use of android.icu.text.TimeZoneFormat.Style in project j2objc by google.

the class SimpleDateFormat method subParse.

/**
 * Protected method that converts one field of the input string into a
 * numeric field value in <code>cal</code>.  Returns -start (for
 * ParsePosition) if failed.  Subclasses may override this method to
 * modify or add parsing capabilities.
 * @param text the time text to be parsed.
 * @param start where to start parsing.
 * @param ch the pattern character for the date field text to be parsed.
 * @param count the count of a pattern character.
 * @param obeyCount if true, then the next field directly abuts this one,
 * and we should use the count to know when to stop parsing.
 * @param ambiguousYear return parameter; upon return, if ambiguousYear[0]
 * is true, then a two-digit year was parsed and may need to be readjusted.
 * @param cal
 * @param numericLeapMonthFormatter if non-null, used to parse numeric leap months.
 * @param tzTimeType the type of parsed time zone - standard, daylight or unknown (output).
 *      This parameter can be null if caller does not need the information.
 * @return the new start position if matching succeeded; a negative
 * number indicating matching failure, otherwise.  As a side effect,
 * set the appropriate field of <code>cal</code> with the parsed
 * value.
 * @deprecated This API is ICU internal only.
 * @hide draft / provisional / internal are hidden on Android
