You can define a dictionary to describe the object, and then return a
sequence of those:
dictionary MyNodeInfo {
Node node;
float number1;
float number2;
float number3;
};
partial interface Document {
sequence<MyNodeInfo> myFunction();
};
Then:
void nsIDocument::MyFunction(nsTArray<MyNodeInfo>& aResult) {
MyNodeInfo* e = aResult.AppendElement();
e->mNode = …;
e->mNumber1 = …;
…
}
