GNU Smalltalk Library Reference: Sockets.StreamSocket-stream protocol

atEnd: Answer whether more data is available on the socket
availableBytes: Answer how many bytes are available in the socket’s read buffer or from the operating system.
bufferContents: Answer the current contents of the read buffer
canRead: Answer whether more data is available in the socket’s read buffer or from the operating system.
close: Flush and close the socket.
fill: Fill the read buffer with data read from the socket
isPeerAlive: Answer whether the connection with the peer remote machine is still valid.
next: Read a byte from the socket. This might yield control to other Smalltalk Processes.
peek: Read a byte from the socket, without advancing the buffer; answer nil if no more data is available. This might yield control to other Smalltalk Processes.
peekFor: anObject: Read a byte from the socket, advancing the buffer only if it matches anObject; answer whether they did match or not. This might yield control to other Smalltalk Processes.
readBufferSize: size: Create a new read buffer of the given size (which is only possible before the first read or if the current buffer is empty).
