Constructor & Destructor Documentation

template<typename C , typename T >
IXE::io::pstream_common< C, T >::pstream_common (  )  [inline, protected]

Default constructor.

Creates an uninitialised stream.

Definition at line 2588 of file pstream.h.

References IXE::io::pstream_common< CharT, Traits >::buf_.

template<typename C , typename T >
IXE::io::pstream_common< C, T >::pstream_common ( const std::string &  command,
pmode  mode 
) [inline, protected]

Constructor that initialises the stream by starting a process.

Initialises the stream buffer by calling do_open( command , mode ).

Parameters:
command a string containing a shell command.
mode the I/O mode to use when opening the pipe.
See also:
do_open(const std::string&, pmode)

Definition at line 2606 of file pstream.h.

References IXE::io::pstream_common< CharT, Traits >::buf_, and IXE::io::pstream_common< CharT, Traits >::do_open().

template<typename C , typename T >
IXE::io::pstream_common< C, T >::pstream_common ( const std::string &  file,
const argv_type argv,
pmode  mode 
) [inline, protected]

Constructor that initialises the stream by starting a process.

Initialises the stream buffer by calling do_open( file , argv , mode ).

Parameters:
file a string containing the pathname of a program to execute.
argv a vector of argument strings passed to the new program.
mode the I/O mode to use when opening the pipe.
See also:
do_open(const std::string&, const argv_type&, pmode)

Definition at line 2626 of file pstream.h.

References IXE::io::pstream_common< CharT, Traits >::buf_, and IXE::io::pstream_common< CharT, Traits >::do_open().

template<typename C , typename T >
IXE::io::pstream_common< C, T >::~pstream_common (  )  [inline, protected, pure virtual]

Pure virtual destructor.

This is a pure virtual function to make pstream_common abstract.

Because it is the destructor it will be called by derived classes and so must be defined. It is also protected, to discourage use of the PStreams classes through pointers or references to the base class.

See also:
If defining a pure virtual seems odd you should read http://www.gotw.ca/gotw/031.htm (and the rest of the site as well!)
