<p class="MsoNormal">Hello Ori,<br>
<br>
You can create different kinds of nodes directly. For example, to create a new namespace, you will need to use code like this:<br>
<br>
IdentifierInfo *IdInfo = Context.Idents.get("bar");<br>
NamespaceDecl *NewNS = NamespaceDecl::Create(Context, Context.getTranslationUnitDecl(), false, StartLoc, IdLoc, IdInfo, OldDecl);<br>
<br>
You can take a look at constructors of different Decl kinds (and static ::Create() methods) in Decl.h and DeclCXX.h (and other Decl*.h) for more information.<br>
To move a function to this namespace, you will need to set a new DeclContext for it:<br>
<br>
FD->setDeclContext(NewNS);<br>
FD->setLexicalDeclContext(NewNS);<br>
<br>
