#include "clang/Lex/MultipleIncludeOpt.h"

Implements the simple state machine that the Lexer class uses to detect files subject to the 'multiple-include' optimization.

The public methods in this class are triggered by various events that occur when a file is lexed, and after the entire file is lexed, information about which macro (if any) controls the header is returned.

Definition at line 28 of file MultipleIncludeOpt.h.

◆ MultipleIncludeOpt() ◆ EnterTopLevelConditional() void clang::MultipleIncludeOpt::EnterTopLevelConditional ( ) inline ◆ EnterTopLevelIfndef()

Called when entering a top-level #ifndef directive (or the "\#if !defined" equivalent) without any preceding tokens.

Note, we don't care about the input value of 'ReadAnyTokens'. The caller ensures that this is only called if there are no tokens read before the #ifndef. The caller is required to do this, because reading the #if line obviously reads in tokens.

◆ ExitTopLevelConditional() void clang::MultipleIncludeOpt::ExitTopLevelConditional ( ) inline ◆ ExpandedMacro() void clang::MultipleIncludeOpt::ExpandedMacro ( ) inline

ExpandedMacro - When a macro is expanded with this lexer as the current buffer, this method is called to disable the MIOpt if needed.

SetReadToken - Set whether the value of 'ReadAnyTokens'.

Called to override when encountering tokens outside of the include guard that have no effect if the file in question is is included multiple times (e.g. the null directive).
