Methods

¶clang::ASTDeserializationListener*
GetASTDeserializationListener()

Description

If the consumer is interested in entities being deserialized from AST files, it should return a pointer to a ASTDeserializationListener here

Declared at: clang/include/clang/Serialization/ASTWriter.h:786

¶clang::ASTMutationListener*
GetASTMutationListener()

Description

If the consumer is interested in entities getting modified after their initial creation, it should return a pointer to an ASTMutationListener here.

Declared at: clang/include/clang/Serialization/ASTWriter.h:785

¶void HandleTranslationUnit(clang::ASTContext& Ctx)

Description

HandleTranslationUnit - This method is called when the ASTs for entire translation unit have been parsed.

Declared at: clang/include/clang/Serialization/ASTWriter.h:784

Parameters

clang::ASTContext& Ctx

¶void InitializeSema(clang::Sema& S)

Description

Initialize the semantic consumer with the Sema instance being used to perform semantic analysis on the abstract syntax tree.

Declared at: clang/include/clang/Serialization/ASTWriter.h:783

Parameters

clang::Sema& S
