I was reading Algorithms in a Nutshell (O'Reilly) and came across this symbol in a class diagram. My guess is that it means the member is protected, but I wanted to see if anyone knows for sure what it means.

It indicates a protected member of a class or other data type.
- Indicates private
+ Indicates public
# Indicates protected
'#' indicates the visibility. In this case it refers to a protected operation [ edited out the term 'method' as this is not as generic ].
4Add also to :
~ Indicates package-private (or default)
It implies that it is protected, for a variable it will only be seen in the class and inherited classes.
'#' stands for visibility "protected" (similar to public,private ) behavior of the property/methods in the class . You can find more of the same at uml_basic_notations
