Method Detail

port

public int port()
Get the port number used by this node.

Returns:
the port number this server node is accepting connections on.

setEpmd

protected void setEpmd(OtpTransport s)
Set the Epmd socket after publishing this nodes listen port to Epmd.

Parameters:
s - The socket connecting this node to Epmd.

getEpmd

protected OtpTransport getEpmd()
Get the Epmd socket.

Returns:
The socket connecting this node to Epmd.

createPid

public OtpErlangPid createPid()
Create an Erlang pid. Erlang pids are based upon some node specific information; this method creates a pid using the information in this node. Each call to this method produces a unique pid.

Returns:
an Erlang pid.

createPort

public OtpErlangPort createPort()
Create an Erlang port. Erlang ports are based upon some node specific information; this method creates a port using the information in this node. Each call to this method produces a unique port. It may not be meaningful to create a port in a non-Erlang environment, but this method is provided for completeness.

Returns:
an Erlang port.

createRef

public OtpErlangRef createRef()
Create an Erlang reference. Erlang references are based upon some node specific information; this method creates a reference using the information in this node. Each call to this method produces a unique reference.

Returns:
an Erlang reference.
