Protected Member Functions | |
pstream_common () | |
Default constructor. | |
pstream_common (const std::string &command, pmode mode) | |
Constructor that initialises the stream by starting a process. | |
pstream_common (const std::string &file, const argv_type &argv, pmode mode) | |
Constructor that initialises the stream by starting a process. | |
virtual | ~pstream_common ()=0 |
Pure virtual destructor. | |
void | do_open (const std::string &command, pmode mode) |
Start a process. | |
void | do_open (const std::string &file, const argv_type &argv, pmode mode) |
Start a process. | |
Protected Attributes | |
std::string | command_ |
The command used to start the process. | |
streambuf_type | buf_ |
The stream buffer. |
Abstract Base Class providing common functionality for basic_ipstream, basic_opstream and basic_pstream. pstream_common manages the basic_pstreambuf stream buffer that is used by the derived classes to initialise an IOStream class.
|
Default constructor. Creates an uninitialised stream. |
|
Constructor that initialises the stream by starting a process. Initialises the stream buffer by calling do_open( command , mode )
|
|
Constructor that initialises the stream by starting a process. Initialises the stream buffer by calling do_open( file , argv , mode )
|
|
Pure virtual destructor.
This is a pure virtual function to make
