Member Functions

copyStream static

static std::streamsize copyStream(
    std::istream & istr,
    std::ostream & ostr,
    std::size_t bufferSize = 8192
);

Writes all bytes readable from istr to ostr, using an internal buffer.

Returns the number of bytes copied.

copyStream64 static

static Poco::UInt64 copyStream64(
    std::istream & istr,
    std::ostream & ostr,
    std::size_t bufferSize = 8192
);

Writes all bytes readable from istr to ostr, using an internal buffer.

Returns the number of bytes copied as a 64-bit unsigned integer.

Note: the only difference to copyStream() is that a 64-bit unsigned integer is used to count the number of bytes copied.

copyStreamUnbuffered static

static std::streamsize copyStreamUnbuffered(
    std::istream & istr,
    std::ostream & ostr
);

Writes all bytes readable from istr to ostr.

Returns the number of bytes copied.

copyStreamUnbuffered64 static

static Poco::UInt64 copyStreamUnbuffered64(
    std::istream & istr,
    std::ostream & ostr
);

Writes all bytes readable from istr to ostr.

Returns the number of bytes copied as a 64-bit unsigned integer.

Note: the only difference to copyStreamUnbuffered() is that a 64-bit unsigned integer is used to count the number of bytes copied.

copyToString static

static std::streamsize copyToString(
    std::istream & istr,
    std::string & str,
    std::size_t bufferSize = 8192
);

Appends all bytes readable from istr to the given string, using an internal buffer.

Returns the number of bytes copied.

copyToString64 static

static Poco::UInt64 copyToString64(
    std::istream & istr,
    std::string & str,
    std::size_t bufferSize = 8192
);

Appends all bytes readable from istr to the given string, using an internal buffer.

Returns the number of bytes copied as a 64-bit unsigned integer.

Note: the only difference to copyToString() is that a 64-bit unsigned integer is used to count the number of bytes copied.
