Was more using the wording from <a href="http://clang.llvm.org/docs/LibASTMatchersReference.html">http://clang.llvm.org/docs/LibASTMatchersReference.html</a></div><div>Was referring to the "returned" objects by the matchers and not the return type of o matcher method on a node. Now going back to this page, I think there is a mistake in the header of the matchers table. I think the "Parameters" should be swapped with the "Return types". Or I am still confused with the wording. Does "parameter" here mean the ast node argument passed to the matcher method? That is recordDecl is applied aggainst Decl and returns CXXRecord? <br>Also after reading through the table few times I discovered that the matcher names are "clickable" and a little doc expands. Probably not so obvious for most people.<br><br><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><span class=""><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div><div>It is impossible to know the real type of the node before matching, as it could be a subclass of what you are matching.<br></div></div></div></blockquote></span></div></div></div></blockquote><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div>A DynTypedMatcher has 2 "Kinds": SupportedKind and RestrictKind.</div></div></div></div></blockquote><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div><br></div><div>SupportedKind is the minimum static type that the matcher accepts.
