parseDateTimeExpression

parseDateTimeExpression() initializes a DateTime object from a string using the given format expression. The format expression is a string with placeholders for date/time variables (see Date and Time Formatting Patterns).

The operation expects that aString conforms to the given format aFormat. If the string does not match with the given format, the xUML Runtime will raise an exception and not parse the string.
If conformity to the format is not guaranteed, you can use the match() Operation on aString to check before using parseDateTimeExpression.

aString

Can be any variable or object attribute having the type String.  

aFormat
