From: Ted Kremenek Date: Wed, 23 Jan 2008 19:57:33 +0000 (+0000) Subject: Added "getRoot()" to ImmutableSet. X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1eed950d7cb69906264cfb49895165e3b51524be;p=oota-llvm.git Added "getRoot()" to ImmutableSet. Made ImmutableSet::ImmutableSet(ImutAVLTree* Root) public. (this allows handy casting between trees and sets). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46277 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/include/llvm/ADT/ImmutableSet.h b/include/llvm/ADT/ImmutableSet.h index 9f08b038fc6..527ef200642 100644 --- a/include/llvm/ADT/ImmutableSet.h +++ b/include/llvm/ADT/ImmutableSet.h @@ -862,14 +862,17 @@ class ImmutableSet { public: typedef typename ValInfo::value_type value_type; typedef typename ValInfo::value_type_ref value_type_ref; - -private: typedef ImutAVLTree TreeTy; + +private: TreeTy* Root; - - ImmutableSet(TreeTy* R) : Root(R) {} - + public: + /// Constructs a set from a pointer to a tree root.
