I've started writing an interface for FedEx's webservice APIs. They have 3 different APIs that I'm interested in; Rate, Ship, and Track. I am generating the service proxies with SvcUtil.exe.
The different service endpoints are each specified by FedEx in their own WSDL files. Each service endpoint has it's own xml namespace (e.g. http...
It is said that when we have a class Point and knows how to perform point * 3 like the following:
class Point
def initialize(x,y)
@x, @y = x, y
end
def *(c)
Point.new(@x * c, @y * c)
end
end
point = Point.new(1,2)
p point
p point * 3
Output:
#<Point:0x336094 @x=1, @y=2>
#<Point:0x335fa4 @x=3, @y=6>
but then,
3...
In Ruby, the operation of
point - 20 # treating it as point - (20,20)
20 - point # treating it as (20,20) - point
are to be implemented.
But the following code:
class Point
attr_accessor :x, :y
def initialize(x,y)
@x, @y = x, y
end
def -(q)
if (q.is_a? Fixnum)
return Point.new(@x - q, @y - q)
end
Poin...
In Ruby, it seems that a lot of coerce() help can be done by
def coerce(something)
[self, something]
end
that's is, when
3 + rational
is needed, Fixnum 3 doesn't know how to handle adding a Rational, so it asks Rational#coerce for help by calling rational.coerce(3), and this coerce instance method will tell the caller:
# I know ...
First I will explain the context of the problem, because you might be able to point me in a better direction.
I need to implement a undo-redo like system on an object. The object has a series of dependency properties. Some are double, int, string but some are also of DependencyObject type.
I need to save the value of the property befor...
Hi all,
I am using R to open up some saved .csv files in a particular pairwise manner and perform a statistical test ("mantel.rtest", found in the package "ade4"). The .csv files are sequentially named as either "fileAX" or "fileBY", where X and Y are integers.
I'd like to save the results of this test in a single file, but am runnin...
I want this code to "just work":
def main():
c = Castable()
print c/3
print 2-c
print c%7
print c**2
print "%s" % c
print "%i" % c
print "%f" % c
Of course, the easy way out is to write int(c)/3, but I'd like to enable a simpler perl-ish syntax for a configuration mini-language.
It's notable that if I ...
