class LineTableInfo

Declaration

class LineTableInfo { /* full declaration omitted */ };

Description

Used to hold and unique data used to represent # line information.

Declared at: clang/include/clang/Basic/SourceManagerInternals.h:80

Member Variables

private llvm::StringMap<unsigned int, llvm::BumpPtrAllocator> FilenameIDs

This allows us to unique the filenames that frequently reoccur and reference them with indices. FilenameIDs holds the mapping from string -> ID, and FilenamesByID holds the mapping of ID to string.

private std::vector<llvm::StringMapEntry<unsigned int>*> FilenamesByID

private std::map<FileID, std::vector<LineEntry>> LineEntries

Map from FileIDs to a list of line entries (sorted by the offset at which they occur in the file).

• public const clang::LineEntry * FindNearestLineEntry(clang::FileID FID, unsigned int Offset)
• public clang::LineTableInfo::iterator begin()
• public void clear()
• public clang::LineTableInfo::iterator end()
• public llvm::StringRef getFilename(unsigned int ID) const
• public unsigned int getLineTableFilenameID(llvm::StringRef Str)
• public unsigned int getNumFilenames() const

Methods

¶void AddEntry(
    clang::FileID FID,
    const std::vector<LineEntry>& Entries)

Description

Add a new line entry that has already been encoded into the internal representation of the line table.

Declared at: clang/include/clang/Basic/SourceManagerInternals.h:128

Parameters

clang::FileID FID

const std::vector<LineEntry>& Entries

¶void AddLineNote(
    clang::FileID FID,
    unsigned int Offset,
    unsigned int LineNo,
    int FilenameID,
    unsigned int EntryExit,
    SrcMgr::CharacteristicKind FileKind)

Declared at: clang/include/clang/Basic/SourceManagerInternals.h:110

Parameters

clang::FileID FID

unsigned int Offset

unsigned int LineNo

int FilenameID

unsigned int EntryExit

SrcMgr::CharacteristicKind FileKind

¶const clang::LineEntry* FindNearestLineEntry(
    clang::FileID FID,
    unsigned int Offset)

Description

Find the line entry nearest to FID that is before it. If there is no line entry before \p Offset in \p FID, returns null.
