Member Function Documentation

BeginInvocation()

virtual bool clang::FrontendAction::BeginInvocation ( CompilerInstance &  CI )

inlineprotectedvirtual

Callback before starting processing a single input, giving the opportunity to modify the CompilerInvocation or do some other action before BeginSourceFileAction is called.

Returns

True on success; on failure BeginSourceFileAction(), ExecuteAction() and EndSourceFileAction() will not be called.

Reimplemented in clang::arcmt::CheckAction, clang::arcmt::ModifyAction, clang::arcmt::MigrateSourceAction, clang::arcmt::MigrateAction, clang::arcmt::ObjCMigrateAction, clang::WrapperFrontendAction, clang::DumpModuleInfoAction, and clang::FixItRecompile.

Definition at line 80 of file FrontendAction.h.

BeginSourceFile()

bool FrontendAction::BeginSourceFile	(	CompilerInstance &	CI,
		const FrontendInputFile &	Input
	)

Prepare the action for processing the input file Input.

This is run after the options and frontend have been initialized, but prior to executing any per-file processing.

Parameters

CI

- The compiler instance this action is being run from. The action may store and use this object up until the matching EndSourceFile action.

Input

- The input filename and kind. Some input kinds are handled specially, for example AST inputs, since the AST file itself contains several objects which would normally be owned by the CompilerInstance. When processing AST input files, these objects should generally not be initialized in the CompilerInstance – they will automatically be shared with the AST file in between BeginSourceFile() and EndSourceFile().

Returns

True on success; on failure the compilation of this file should be aborted and neither Execute() nor EndSourceFile() should be called.
