Class TcpEndpoint.ConnectionEndpointImpl

java.lang.Object

net.jini.jeri.tcp.TcpEndpoint.ConnectionEndpointImpl

All Implemented Interfaces:

ConnectionEndpoint

Enclosing class:

TcpEndpoint

private class TcpEndpoint.ConnectionEndpointImpl
extends Object
implements ConnectionEndpoint

ConnectionEndpoint implementation. Instances of this class should never get exposed to anything other than our ConnectionManager, which we trust to operate correctly, so we do not bother to validate request handles and connections passed in.

Method Detail

connect

public Connection connect(OutboundRequestHandle handle)
                   throws IOException

Invoked by ConnectionManager to create a new connection.

Specified by:

connect in interface ConnectionEndpoint

Parameters:

handle - the handle for the request

Returns:

a new connection that can be used to send a request for the specified handle

Throws:

IOException - if an I/O exception occurs

connectToHost

private Socket connectToHost(Constraints.Distilled distilled)
                      throws IOException

Returns a socket connected to this endpoint's host and port, according the specified constraints. If the host name resolves to multiple addresses, attempts to connect to each of them in order until one succeeds.

Throws:

IOException

connectToSocketAddress

private Socket connectToSocketAddress(SocketAddress socketAddress,
                            Constraints.Distilled distilled)
                               throws IOException

Returns a socket connected to the specified address, with a timeout governed by the specified constraints.

Throws:

IOException

newSocket

private Socket newSocket()
                  throws IOException

Returns a new unconnected socket, using this endpoint's socket factory if non-null.

Throws:

IOException

connect

public Connection connect(OutboundRequestHandle handle,
                 Collection active,
                 Collection idle)

Invoked by ConnectionManager to reuse an existing connection.

Specified by:

connect in interface ConnectionEndpoint

Parameters:

handle - the handle for the request

active - the connections with requests in progress

idle - the connections with no requests in progress

Returns:

a connection that can be used to send an outbound request for the specified handle, or null

checkResolvePermission

private void checkResolvePermission()
