Description
This is the streambuf class used for reading from and writing to a FIFOBuffer. FIFOBuffer is enabled for emtpy/non-empty/full state transitions notifications.

Constructors
FIFOBufferStreamBuf
Creates a FIFOBufferStreamBuf.
FIFOBufferStreamBuf
explicit FIFOBufferStreamBuf(
FIFOBuffer & fifoBuffer
);
Creates a FIFOBufferStreamBuf and assigns the given buffer to it.
FIFOBufferStreamBuf
explicit FIFOBufferStreamBuf(
std::size_t length
);
Creates a FIFOBufferStreamBuf of the given length.
FIFOBufferStreamBuf
FIFOBufferStreamBuf(
char * pBuffer,
std::size_t length
);
Creates a FIFOBufferStreamBuf and assigns the given buffer to it.
FIFOBufferStreamBuf
FIFOBufferStreamBuf(
const char * pBuffer,
std::size_t length
);
Creates a FIFOBufferStreamBuf and assigns the given buffer to it.
Destructor
~FIFOBufferStreamBuf
~FIFOBufferStreamBuf() override;
Destroys the FIFOBufferStreamBuf.
