Description Dirk Baeumer CLA 2003-09-18 06:03:33 EDT 
I20030917

In the following example:

package p;

class A{
	class Inner{
	}
}
class B extends A.Inner{
	B(){
		new A().super();
	}
}

Searching for the implicit constructor Inner using the string 
pattern "p.A.Inner.Inner()" will result in no match. How do we search for 
implicit constructors in this case.
Comment 1 Philipe Mulet CLA 2003-09-18 08:58:59 EDT 
Default constructors are not existing in source, thus you can neither find them 
in sources nor get access to these when navigating through the JavaModel.

What kind of an element would you expect ? Since you cannot see it in the 
outliner anyway...
Comment 2 Dirk Baeumer CLA 2003-09-18 11:53:40 EDT 
But you can reference them in source. So there should be a way to find all 
references of a default constructor even if it doesn't exist in source.

IMO, the search result contains the enclosing element and the positions not 
the element itself, which is fine when searching for references.
Comment 3 Philipe Mulet CLA 2003-09-24 03:52:49 EDT 
References should work I agree, but declaration matches should not as they 
don't exist in the source.
Comment 4 Dirk Baeumer CLA 2003-09-24 04:45:42 EDT 
Agree, that we can't expect to find declarations for default constructors.
Comment 5 Philipe Mulet CLA 2003-09-24 07:50:17 EDT 
Searching for ""p.A.Inner()" works.
Comment 6 Philipe Mulet CLA 2003-09-24 07:57:20 EDT 
See the spec on SearchEngine:

 *  	<li>search for case sensitive references to exact <code>Object()</code> 
constructor:
 *			<code>createSearchPattern("java.lang.Object()", 
CONSTRUCTOR, REFERENCES, true);</code></li>

Closing.
Comment 7 Dirk Baeumer CLA 2003-09-24 09:07:31 EDT 
Thanks.

Why is this inconsistent to methods:  p.A.Inner.foo() is the pattern for 
method foo but p.A.Inner.Inner() isn't the pattern for default constructors.
Comment 8 Philipe Mulet CLA 2003-09-24 09:17:49 EDT 
Invoking a constructor doesn't require you to type new X.X() either...
