/*
|
|
* No magic constructor behaviour, as is de rigeur for XPCOM.
|
|
* If you must perform some initialization, and it could possibly fail (even
|
|
* due to an out-of-memory condition), you should use an Init method, which
|
|
* can convey failure appropriately (thrown exception in JS,
|
|
* NS_FAILED(nsresult) return in C++).
|
|
*
|
|
* In JS, you can actually cheat, because a thrown exception will cause the
|
|
* CreateInstance call to fail in turn, but not all languages are so lucky.
|
|
* (Though ANSI C++ provides exceptions, they are verboten in Mozilla code
|
|
* for portability reasons -- and even when you're building completely
|
|
* platform-specific code, you can't throw across an XPCOM method boundary.)
