Detailed Description
template<typename T, typename OffsT, T *(ExternalASTSource::*)(OffsT Offset) Get>
struct clang::LazyOffsetPtr< T, OffsT, Get >
A lazy pointer to an AST node (of base type T) that resides within an external AST source.
The AST node is identified within the external AST source by a 63-bit offset, and can be retrieved via an operation on the external AST source itself.

Member Data Documentation
uint64_t clang::LazyOffsetPtr< T, OffsT, Get >::Ptr [mutable] |
Either a pointer to an AST node or the offset within the external AST source where the AST node can be found.
If the low bit is clear, a pointer to the AST node. If the low bit is set, the upper 63 bits are the offset.
