static final ByteBuffer EMPTY_BUFFER

A handy constant to use for no-op send/receive calls.

Method Details

init

void init(@NonNull
 ProtocolStack<?>.Ptr ptr)
   throws IOException

Initializes the layer with its ProtocolStack.Ptr. All lower layers in the stack will be initialized before a call to this method. All layers in a stack will be initialized before a call to start().

Parameters:

ptr - the position of this layer in the stack.

Throws:

IOException - if something goes wrong.

start

void start()
    throws IOException

Starts this layer. All layers in the stack will be initialized before a call to this method. All lower layers in the stack will have been started before this layer is started.

Throws:

IOException - if something goes wrong.
