isStrictFormatCheck

public boolean isStrictFormatCheck()
Strict format check defines whether the set pattern should be exactly by format, or be more flexibel in analysing the given date. This has nothing to do with lenient in SimpleDateFormat.

MMMM.yyyy HH:mm 01.01.2016 01.Januar.2016 00:00 01.Jänner.2016 01.01 01.01.16 01.01 01 01 2016 00 00 010116 01012016 The result will always be 01.Januar.2016 00:00

Returns:
true, if format should be checked strict.

setStrictFormatCheck

public void setStrictFormatCheck(boolean pStrictFormatCheck)
Strict format check defines whether the set pattern should be exactly by format, or be more flexibel in analysing the given date. This has nothing to do with lenient in SimpleDateFormat. Lenient is set to false anyway. Only correct dates are allowed. The following will be allowed without strict check, with locale de_AT and pattern: dd. MMMM.yyyy HH:mm 01.01.2016 01.Januar.2016 00:00 01.Jänner.2016 01.01 01.01.16 01.01 01 01 2016 00 00 010116 01012016 The result will always be 01.Januar.2016 00:00
