Description
The base class for PartialInputStream and PartialOutputStream.
This class is needed to ensure the correct initialization order of the stream buffer and base classes.
Inheritance
Direct Base Classes: std::ios
All Base Classes: std::ios
Known Derived Classes: PartialInputStream, PartialOutputStream
Member Summary
Member Functions: rdbuf
Constructors
PartialIOS
PartialIOS(
std::ostream & ostr,
std::size_t start,
std::size_t end,
bool initStream
);
Creates the basic stream and connects it to the given output stream. If initStream is true the status of the stream will be cleared on the first access. start and end acts as offset values for the written content. A start value greater than zero, means that the first bytes are not written but discarded instead, an end value not equal to zero means that the last end bytes are not written! Examples:
start = 3; end = 1
write("hello", 5) -> "l"
PartialIOS
PartialIOS(
std::istream & istr,
std::ios::pos_type start,
std::ios::pos_type end,
const std::string & prefix,
const std::string & postfix,
bool initStream
);
Creates the basic stream and connects it to the given input stream. If initStream is true the status of the stream will be cleared on the first access, and the stream will be repositioned to position start
Destructor
~PartialIOS
~PartialIOS();
Destroys the stream.
Member Functions
rdbuf
PartialStreamBuf * rdbuf();
Returns a pointer to the underlying streambuf.
Variables
_buf 
PartialStreamBuf _buf;
