Detailed Description

GlobalDeclID means DeclID in the current ASTContext and LocalDeclID means DeclID specific to a certain ModuleFile.

Specially, in ASTWriter, the LocalDeclID to the ModuleFile been writting is equal to the GlobalDeclID. Outside the serializer, all the DeclID been used should be GlobalDeclID. We can translate a LocalDeclID to the GlobalDeclID by ASTReader::getGlobalDeclID().

Member Typedef Documentation

◆ DeclID

using clang::DeclIDBase::DeclID = uint64_t

An ID number that refers to a declaration in an AST file.

The ID numbers of declarations are consecutive (in order of discovery), with values below NUM_PREDEF_DECL_IDS being reserved. At the start of a chain of precompiled headers, declaration ID 1 is used for the translation unit declaration.

DeclID should only be used directly in serialization. All other users should use LocalDeclID or GlobalDeclID.
