Member Function Documentation

AllowStatCache()

void RealDiskInterface::AllowStatCache

(

bool

allow

)

Whether stat information can be cached. Only has an effect on Windows.

Definition at line 281 of file disk_interface.cc.

MakeDir()

bool RealDiskInterface::MakeDir ( const std::string &  path )

virtual

Create a directory, returning false on failure.

Implements DiskInterface.

Definition at line 246 of file disk_interface.cc.

References Error().

MakeDirs()

bool DiskInterface::MakeDirs ( const std::string &  path )

inherited

Create all the parent directories for path; like mkdir -p basename path.

Definition at line 138 of file disk_interface.cc.

References Error().

Referenced by Builder::StartEdge().

ReadFile()

FileReader::Status RealDiskInterface::ReadFile ( const std::string &  path, std::string *  contents, std::string *  err  )

virtual

Read and store in given string.

On success, return Okay. On error, return another Status and fill |err|.

Implements FileReader.

Definition at line 257 of file disk_interface.cc.

References ReadFile().

RemoveFile()

int RealDiskInterface::RemoveFile ( const std::string &  path )

virtual

Remove the file named path.

It behaves like 'rm -f path' so no errors are reported if it does not exists.

Returns

0 if the file has been removed, 1 if the file does not exist, and -1 if an error occurs.

Implements DiskInterface.

Definition at line 267 of file disk_interface.cc.

References Error().

Stat()

TimeStamp RealDiskInterface::Stat ( const std::string &  path, std::string *  err  ) const

virtual

stat() a file, returning the mtime, or 0 if missing and -1 on other errors.

Implements DiskInterface.

Definition at line 160 of file disk_interface.cc.

References METRIC_RECORD.

Referenced by WriteFakeManifests().

WriteFile()

bool RealDiskInterface::WriteFile ( const std::string &  path, const std::string &  contents  )

virtual

Create a file, with the specified name and contents Returns true on success, false on failure.

Implements DiskInterface.
