Constructor & Destructor Documentation

OW_NAMESPACE::BaseStreamBuffer::BaseStreamBuffer (  size_t  bufSize = BASE_BUF_SIZE, const char *  direction = "io" )

Create a base stream buffer. TODO: Make a different version of this ctor that doesn't use strings. Use an enum instead. Parameters: bufSize  size of buffer direction  "in", "out", or "io" Definition at line 47 of file OW_BaseStreamBuffer.cpp. References initGetBuffer(), m_bufSize, and m_inputBuffer.

Member Function Documentation

int OW_NAMESPACE::BaseStreamBuffer::buffer_from_device (  char *  c, int  n )  [protected, virtual]

Fill the buffer from the "device". Parameters: c  A pointer to the beginning of the buffer n  The number of bytes to be read into the buffer. Returns: -1 if no bytes are able to be read from the "device" (for instance, end of input stream). Otherwise, return the number of bytes read into the buffer. Reimplemented in OW_NAMESPACE::IOIFCStreamBuffer, OW_NAMESPACE::HTTPChunkedIStreamBuffer, and OW_NAMESPACE::HTTPLengthLimitStreamBuffer.

int OW_NAMESPACE::BaseStreamBuffer::buffer_to_device (  const char *  c, int  n )  [protected, virtual]

Writes the buffer to the "device". Parameters: c  A pointer to the start of the buffer n  the number of bytes to write Returns: -1 if error, 0 if the entire buffer was written.
