Parameters s:String the string to parse cal:Calendar the calendar (or null to use the default calendar) Returns:Date a `Date` value that represents the date in the calendar `cal` Exceptions IllegalArgumentException: if the format of the string is invalid

private static Date date_valueOf(String s, Calendar cal)

Convert a string to a date in the specified calendar. Accept the same format as Date.valueOf().

Parameters

s:String: the string to parse
cal:Calendar: the calendar (or null to use the default calendar)

Returns:Date

a Date value that represents the date in the calendar cal

Exceptions

getBooleanFromString	back to summary
pack-priv final boolean getBooleanFromString(String source) Get a boolean value from a CHAR column. In order to match the embedded driver and JCC we return false iff the CHAR value is "0" or "false". Leading and trailing whitespace is removed from the input string before it's compared to "0" and "false". No other normalization is performed. Specifically, no case conversion is performed, so the comparison is case sensitive, and everything that doesn't exactly match "0" or "false" will be considered true. Parameters source:String the value of a CHAR column Returns:boolean false if source is "0" or "false", true otherwise
