Methods

¶std::unique_ptr<ASTConsumer> CreateASTConsumer(
    clang::CompilerInstance& CI,
    llvm::StringRef InFile)

Description

Create the AST consumer object for this action, if supported. This routine is called as part of BeginSourceFile(), which will fail if the AST consumer cannot be created. This will not be called if the action has indicated that it only uses the preprocessor.

Declared at: clang/include/clang/Frontend/FrontendActions.h:212

Parameters

clang::CompilerInstance& CI

- The current compiler instance, provided as a convenience, see getCompilerInstance().

llvm::StringRef InFile

- The current input file, provided as a convenience, see getCurrentFile().

Returns

The new AST consumer, or null on failure.

¶void ExecuteAction()

Description

Implement the ExecuteAction interface by running Sema on the already-initialized AST consumer. This will also take care of instantiating a code completion consumer if the user requested it and the action supports it.

Declared at: clang/include/clang/Frontend/FrontendActions.h:215

¶bool hasCodeCompletionSupport() const

Description

Does this action support use with code completion?
