When you perform the ParseInt operation with the radix, the 11 base 16 is parsed as 17, which is a simple value. It is then printed as radix 10. You want: System.out.println(Integer.toString(11, 16)); This takes the decimal value 11(not having a base at the moment, like having “eleven” watermelons(one more than the number of fingers … Read more
Lame really isn’t difficult to use, although there are a lot of optional configuration functions if you need them. It takes slightly more than 4-5 lines to encode a file, but not much more. Here is a working example I knocked together (just the basic functionality, no error checking): #include <stdio.h> #include <lame/lame.h> int main(void) … Read more
Vue 3 Same as the Vue 2.6 example below except: $listeners has been merged into $attrs so v-on=”$listeners” is no longer necessary. See the migration guide. $scopedSlots is now just $slots. See migration guide. Vue 2.6 (v-slot syntax) All ordinary slots will be added to scoped slots, so you only need to do this: <wrapper> … Read more
Special methods (essentially anything with two underscores on each end) have to be defined on the class. The internal lookup procedure for special methods completely skips the instance dict. Among other things, this is so if you do class Foo(object): def __repr__(self): return ‘Foo()’ the __repr__ method you defined is only used for instances of … Read more
http://www.codeproject.com/KB/mcpp/quickcppcli.aspx#A8 This is general direction. You need to create C++/CLI Class Library project, add .NET class to it (StudentWrapper in this sample), create unmanaged class instance as managed class member, and wrap every unmanaged class function. Unmanaged library is added to C++/CLI project using linker dependencies list, and not as reference. In the Project – … Read more
An elegant way to do it is described in Michael Foord’s Voidspace blog in an entry about what metaclasses are and how to use them in the section titled A Method Decorating Metaclass. Simplifying it slightly and applying it to your situation resulted in this: from functools import wraps from types import FunctionType def wrapper(method): … Read more
Integers are cached for values between -128 and 127 so Integer i = 127 will always return the same reference. Integer j = 128 will not necessarily do so. You will then need to use equals to test for equality of the underlying int. This is part of the Java Language Specification: If the value … Read more
The key to the answer is called object interning. Java interns small numbers (less than 128), so all instances of Integer(n) with n in the interned range are the same. Numbers greater than or equal to 128 are not interned, hence Integer(1000) objects are not equal to each other.
Decorate the class with a function that walks through the class’s attributes and decorates callables. This may be the wrong thing to do if you have class variables that may happen to be callable, and will also decorate nested classes (credits to Sven Marnach for pointing this out) but generally it’s a rather clean and … Read more
You can’t do it with an alias, because PowerShell aliases can only refer to another command name or path, and can therefore neither include arguments nor custom logic. Therefore you do need a function, but it can be a short and simple one: function which { if ($args.count) { Get-Command @args } else { Throw … Read more
