Made the ctor for ImmutableMap to construct a map from an AVL tree public. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45756 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/ADT/ImmutableMap.h | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-) diff --git a/include/llvm/ADT/ImmutableMap.h b/include/llvm/ADT/ImmutableMap.h index ac4f165..24aef7c 100644 --- a/include/llvm/ADT/ImmutableMap.h +++ b/include/llvm/ADT/ImmutableMap.h @@ -52,20 +52,24 @@ struct ImutKeyValueInfo { template > class ImmutableMap { +public: typedef typename ValInfo::value_type value_type; typedef typename ValInfo::value_type_ref value_type_ref; typedef typename ValInfo::key_type key_type; typedef typename ValInfo::key_type_ref key_type_ref; typedef typename ValInfo::data_type data_type; typedef typename ValInfo::data_type_ref data_type_ref; + typedef ImutAVLTree TreeTy; -private: - typedef ImutAVLTree TreeTy; +private: TreeTy* Root; - - ImmutableMap(TreeTy* R) : Root(R) {} - + public: + /// Constructs a map from a pointer to a tree root.
