CompleteType (ObjCInterfaceDecl *Class)
Gives the external AST source an opportunity to complete an incomplete Objective-C class.
virtual void
ReadComments ()
Loads comment ranges.
virtual void
Notify ExternalASTSource that we started deserialization of a decl or type so until FinishedDeserializing is called there may be decls that are initializing.
virtual void
Notify ExternalASTSource that we finished the deserialization of a decl or type.
virtual void
StartTranslationUnit (ASTConsumer *Consumer)

getMemoryBufferSizes () const
Return the amount of memory used by memory buffers, breaking down by heap-backed versus mmap'ed memory.
virtual void
getMemoryBufferSizes (MemoryBufferSizes &sizes) const
virtual bool
isA (const void *ClassID) const
LLVM-style RTTI.
Definition at line 220 of file CodeCompletion.cpp.
Find all declarations with the given name in the given context, and add them to the context by calling SetExternalVisibleDeclsForName or SetNoExternalVisibleDeclsForName.
Parameters
| DC | The context for lookup in. DC should be a primary context. |
|---|---|
| Name | The name to look for. |
| OriginalDC | The original context for lookup. OriginalDC can provide more information than DC. e.g., The same namespace can appear in multiple module units. So we need the OriginalDC to tell us what the module the lookup come from. |
Returns
true if any declarations might have been found, false if we definitely have no declarations with tbis name.
The default implementation of this method is a no-op returning false.
Reimplemented from clang::ExternalASTSource.
