Guys what is the formal name PRECONDITION or PRECONDITIONS that fnc must satisfy in order to work correctly?
"precondition" when it's one, "preconditions" when it's more than one?

I'm trying to understand the meaning of metric type "MeanSquaredErrorMetric" used in "compare_channel" method of Rmagick, but I do not see a document that explains the meaning of this metric type.
Please help explain for me? Thanks so much.
diff_img, diff_metric = img1[0].compare_channel( img2[0], Magick::MeanSquaredErrorMetric )
Check out the "Comparison Statistics" section on this page.
i found one method ImageFigure() in draw2d. So i want to know is it presnt in graphiti.js also. If it present in graphiti then it solves my problem on grouping object.
Thanks In advance.
ImageShape or ImageFigure is not part of the current graphiti version. Graphiti tries to implement almost all functions/object from Draw2D......but it requires some time.
As the question says, is there any function or module that performs the functionality of inet_addr ?
Results from google isnt suggesting any direct way or am i missing something ?
Thanks.
You can use inet_parse:address, and then convert the resuting list to binary. e.g.
16> list_to_binary(tuple_to_list(element(2,inet_parse:address("192.168.42.2")))).
<<192,168,42,2>>
I want to find out whether a variable is an array or not
if (params.writtenLines == ???)
Much appreciated.
More importantly, why do you want to check whether it's an array? If you know the parameter might be a single string or a list, you can now use:
def lines = params.list("writtenLines")
That came with Grails 1.2.
This functionality is already available in pure Java and can therefore be used in Groovy, too:
if (params.writtenLines.class.isArray())
I realize this is a bit late, but what about this:
List.isCase(params.writtenLines)
Wouldn't it be a correct solution, too?
