While initialization the anonymous struct is only known under its type name (in your case A). The members and functions associated with the struct are only exported to the outside after the instance exists. You have to supply a valid instance of A to initialize MemberA: b := B { A: A{MemberA: “test1”}, MemberB: “test2”, … Read more
Original C++03 answer: The benefit from a namespace (over a class) is that you can use using declarations when you want. The problem with using a namespace is that namespaces can be expanded elsewhere in the code. In a large project, you would not be guaranteed that two distinct enums don’t both think they are … Read more
It looks like you want to loop though the .actions, so change this: $.each(data, function(entryIndex, entry) { var html=”<li class=”top-level”>”; }); To this: $.each(data.actions, function(entryIndex, entry) { var html=”<li class=”top-level”>” + this.action + ‘</li>’; }); Using data.actions you’re now looping through that array of objects, and those objects are the ones with the .action property, … Read more
(1) Nested parallelism in OpenMP: http://docs.oracle.com/cd/E19205-01/819-5270/aewbc/index.html You need to turn on nested parallelism by setting OMP_NESTED or omp_set_nested because many implementations turn off this feature by default, even some implementations didn’t support nested parallelism fully. If turned on, whenever you meet parallel for, OpenMP will create the number of threads as defined in OMP_NUM_THREADS. So, … Read more
As of Solr 4.7 and 4.8, Solr supports nested documents: { “id”: “chapter1”, “title” : “Indexing Child Documents in JSON”, “content_type”: “chapter”, “_childDocuments_”: [ { “id”: “1-1”, “content_type”: “page”, “text”: “ho hum… this is page 1 of chapter 1” }, { “id”: “1-2”, “content_type”: “page”, “text”: “more text… this is page 2 of chapter 1” … Read more
The bytecode of the Outer$Inner class will contain a package-scoped field named this$0 of type Outer. That’s how non-static inner classes are implemented in Java, because at bytecode level there is no concept of an inner class. You should be able to read that field using reflection, if you really want to. I have never … Read more
You are basically creating a closure. In computer science, a closure is a first-class function with free variables that are bound in the lexical environment. Such a function is said to be “closed over” its free variables. Related reading: Closures: why are they so useful? A closure is simply a more convenient way to give … Read more
The & character has the function of a this keyword, actually (a thing I did not know at the moment of writing the answer). It is possible to write: .class1 { &.class2 {} } and the CSS that will be generated will look like this: .class1.class2 {} For the record, @grobitto was the first to … Read more
As of Python 3, the traceback is stored in the exception, so a simple raise e will do the (mostly) right thing: try: something() except SomeError as e: try: plan_B() except AlsoFailsError: raise e # or raise e from None – see below The traceback produced will include an additional notice that SomeError occurred while … Read more
You can use something like this: >>> def lookup(dic, key, *keys): … if keys: … return lookup(dic.get(key, {}), *keys) … return dic.get(key) … >>> d = {‘a’:{‘b’:{‘c’:5}}} >>> print lookup(d, ‘a’, ‘b’, ‘c’) 5 >>> print lookup(d, ‘a’, ‘c’) None Additionally, if you don’t want to define your search keys as individual parameters, you can … Read more
