Member Function Documentation

CreateASTConsumer()

std::unique_ptr< ASTConsumer > ASTPrintAction::CreateASTConsumer ( CompilerInstance &  CI, StringRef  InFile  )

overrideprotectedvirtual

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.

Parameters

CI	- The current compiler instance, provided as a convenience, see getCompilerInstance().
InFile	- The current input file, provided as a convenience, see getCurrentFile().

Returns

The new AST consumer, or null on failure.

Implements clang::FrontendAction.
