Check/Xtend: Regular Expression syntax [message #486335]

Dear Xtend folks,

could you point me to some reference on the Syntax for regular
expressions for Strings in Xtend and Check?

I want to use e.g.

name.matches("MyRegex");

Where MyRegex is a regular expression. I tried to follow the Java Syntax
( http://java.sun.com/javase/6/docs/api/java/util/regex/Patter n.html ) like

name.matches("\w*");

to make sure that something only consists of word characters.
Unfortunately the syntax seems to be different.

Google didn't show me the way and the old oAW document also not
( http://www.openarchitectureware.org/pub/documentation/4.3.1/ html/contents/core_reference.html#r10_expressions_language
)

Cheers,
Hauke

Unfortunately, you have to double the backslashes.

So it is :
name.matches("\\w*");

Regards,
Sven
