Member Function Documentation

bool RealDiskInterface::MakeDir ( const string &  path )

virtual

Create a directory, returning false on failure.

Implements DiskInterface.

Definition at line 147 of file disk_interface.cc.

References Error().

bool DiskInterface::MakeDirs ( const string &  path )

inherited

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

string RealDiskInterface::ReadFile ( const string &  path, string *  err  )

virtual

Read a file to a string. Fill in |err| on error.

Implements DiskInterface.

Definition at line 155 of file disk_interface.cc.

int RealDiskInterface::RemoveFile ( const 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.

TimeStamp RealDiskInterface::Stat ( const string &  path )

virtual

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

Implements DiskInterface.

Definition at line 78 of file disk_interface.cc.

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