|Related to : Compile Error, Member is not a member of a union | working with pointers/structs|
|C++ Member Reference base type 'Vertex *const' is not a structure or union|
vit is an iterator. Iteratirs work like pointers to container
elements. Your container element type is Vertex*. Therefore vit works
To call a member function given a Vertex** p you would have to get to
a Vertex* first. This can be done by dereferencing p like this:
and at this point you can call your member function like
Iterators are no different.
|Template Member function cannot see non-templated class member correctly|
Check your default constructor, copy constructor, and any other custom
constructors/move/operator functions you write/overload. Make sure
these are doing what you think they are doing.
Templated functions work just fine in non-templated classes. Data
being inaccurate or missing is most likely a copy issue.
Edit: As pmr mentions below... Obey the rule of five. That is
definitely the main point.
|Ember.js working with single member of child enumerable|
You really only have two options: search through the array, or store
the one that is currently being edited. If you don't want to store the
one being edited, just use the findBy method to get the object that is
var items = this.get('items');
var editingItem = items.findBy('isEditing', true);
// I use tryInvoke in case one isn't found. That might not be possible
|error: value saveAsTextFile is not a member of Unit|
foreach is, as Ryan pointed out, solely for side-effects. It returns
Unit and not the List itself. Ergo no chaining.
Now what you are actually doing is the following:
val output = ranks.collect()
val realoutput: Unit = output.foreach(tup => println(tup._1 + " has
page rank: " + tup._2))
saveAsTextFile is not a member of Unit and you get your error message
|C++, Class: Out-of-line declaration of a member error?|
You should remove the semicolons in the cpp file.
void Array::addTings (float itemValue);
void Array::addTings (float itemValue)
Correct code is:
void Array::addTings (float itemValue) // Out-of-line declaration
std::cout << "How many items do you want to add to the array";
std::cin >> arraySize;
float Array::getTings (int index) // Out-of-line declara
