isDelimiter

isDelimiter(): Boolean;

The isDelimiter method of the Character primitive type returns true if the receiver is not alphanumeric; otherwise, it returns false.

The code fragment in the following example shows the use of the isDelimiter method.

// find delimiter
count := int;
while count < self.length do
    charValue := self[count];
    if charValue.isDelimiter and charValue <> '_' then
        break;
    else
        count := count + 1;
    endif;
endwhile;
