Little Sugar : Showing an Eclipse view

You can use an IWorkbenchPage.showView(viewId) to programatically show a view .

To access the current active page you can use the following code

IWorkbench workbench = PlatformUI.getWorkbench();
IWorkbenchWindow workbenchWindow = workbench.getActiveWorkbenchWindow();
IWorkbenchPage activePage = workbenchWindow.getActivePage();

Little Sugar : Eclipse Views live in pages

In eclipse we have a workbench window in which different types of pages exist .

thats is WorkbenchWindow > Pages
> ActivePage

a workbench window also contains the currently active page .

Each page is a IWorkbenchPage. A WorkbenchPage contains many views .
Each view is a IViewPart.

So Views live in pages and pages live in workbench window

Little Sugar : Why constantness helps

Say u have a method like this :

const Rational operator*(const Rational& lhs,
                        const Rational& rhs);


Now consider this (a * b ) = c

If the above method returned a non const object then the above mentioned
assignment would make sense , ideally it should not as it would be violating the
api contract for built ins.

Little Sugar : Pointers to Member Functions

Pointers to member functions is a feature that not many people use but its good to know .
So lets have a look at it . Lets assume you have a class

class Person ;

typedef void (Person::*PPMF)();

class Person{
public :
static PPMF blahFunction(){
return &(Person::processAddress);
}

private :
Address address;
void processAddress();

};

Here blah function returns a pointer to the member function processAddress .
Now you have the pointer to the member address , even if it private ( its evil to to access private member function like this) you can invoke this member function now on an instance of a person
class.

Person boo;

eg. PPMF pmf = boo.blahFunction();

invoke the member function like this :

(boo.*pmf)();
