Examples of com.ibm.icu.text.MessageFormat.toPattern()

com.ibm.icu.text.MessageFormat.toPattern()
Returns a pattern representing the current state of the message format. The string is constructed from internal information and therefore does not necessarily equal the previously applied pattern. @return a pattern representing the current state of the message format @stable ICU 3.0
