Detailed Description

Bidirectional stream to external data.

Constructor & Destructor Documentation

ExternalDataSource::ExternalDataSource ( FILE *  inputfile = 0,
FILE *  outputfile = 0 
)

Create a new instance.

Parameters:
inputfile The stream for reading
outputfile The stream for writing Either can be NULL if no reading/writing is allowed.

ExternalDataSource::~ExternalDataSource (  )  [virtual]

Implicitly close the connection.

Member Function Documentation

int ExternalDataSource::close (  )  [virtual]

Close the input and output streams.

Reimplemented in ExternalProgram.

References inputfile, and outputfile.

Referenced by ~ExternalDataSource().

FILE* ExternalDataSource::inputFile (  )  const [inline]

Return the input stream.

References inputfile.

FILE* ExternalDataSource::outputFile (  )  const [inline]

Return the output stream.

References outputfile.

Referenced by main().

size_t ExternalDataSource::receive ( char *  buffer,
size_t  length 
)

Read some data from the input stream.

Parameters:
buffer Where to put the data
length How much to read at most Returns the amount actually received

References inputfile.

Referenced by Process::readStdoutToBuffer().

string ExternalDataSource::receiveLine (  ) 

Read one line from the input stream. Returns the line read, including the terminator.

References stringutil::getline(), inputfile, linebuffer, and linebuffer_size.

Referenced by PathInfo::clean_dir(), PathInfo::copy(), PathInfo::copy_dir(), PathInfo::copy_file2dir(), and PathInfo::recursive_rmdir().

string ExternalDataSource::receiveUpto ( char  c  ) 

Read characters into a string until character c is read. C is put at the end of the string.

References inputfile.

Referenced by Process::BufferNewStdoutLines().

bool ExternalDataSource::send ( std::string  s  ) 

Send some data down the stream.

Parameters:
string The data to send

References DBG, and send().

bool ExternalDataSource::send ( const char *  buffer,
size_t  length 
)

Send some data to the output stream.

Parameters:
buffer The data to send
length The size of it

References outputfile.

Referenced by main(), and send().

void ExternalDataSource::setBlocking ( bool  mode  ) 

Set the blocking mode of the input stream.

Parameters:
mode True if the reader should be blocked waiting for input. This is the initial default.
