Extension Point question [message #312209]

Hi,
I have declared an extension point in my plugin. In the schema (.exsd) file,
I specify an Interface that the
user of the extension point must implement.

I use this extension point from another plugin - and instead of implementing
the interface specified in the (.exsd),
i used some other interface ( by mistake ). But no error was thrown at
runtime. The class specified in the extension
point loaded even though it implemented some other interface . Am i missing
something or is the schema file never checked
at runtime. How can such a check be enforced ?

Thanks

You can do something similar the following:
Interface yourObject = (Interface)
configurationElement.createExecutableExtension("YOUR_CLASS_ATTRIBUTE ");

or

Object yourObject =
configurationElement.createExecutableExtension("YOUR_CLASS_ATTRIBUTE ");
if (object instanceof Interface)
....

Light bulb and error markers overlapping [message #312478 is a reply to message #312209]

I remember changing a preference that made the light bulb and other
markers to the left of the line numbers in editors collapse into one. I
have to point at them for a second or two before they open so that I can
select one of them.

I can't remember how to change this back to the default. I looked
through the preferences with no luck. Any ideas?

Thanks,
Shahim
