public class LoopbackPortHub
extends Object
implements PortHub<LoopbackPort,PortMetrics>

public LoopbackPortHub()

Constructs an empty LoopbackPortHub. Add ports by calling toPort(String).

LoopbackPortHub

public LoopbackPortHub(String... aPorts)

Constructs the LoopbackPortHub with the given ports (e.g. ports with the given port aliases).

Parameters:

aPorts - The aliases for the ports to be contained within this PortHub.

Method Detail

ports

public LoopbackPort[] ports()
                     throws IOException

Lists the available TTY-/COM-Ports of the system.

Specified by:

ports in interface PortHub<LoopbackPort,PortMetrics>

Returns:

An array of available Port instances.

Throws:

IOException - Thrown in case accessing the list of Port instances failed due to I/O problems.

toPort

public LoopbackPort toPort(String aAlias)
                    throws NoSuchPortExcpetion,
                           IOException

Returns the Port identified by the given alias.

Specified by:

toPort in interface PortHub<LoopbackPort,PortMetrics>

Parameters:

aAlias - The alias identifying the given Port.

Returns:

The given Port.

Throws:

NoSuchPortExcpetion - thrown in case there is no such port found.

IOException - Thrown in case accessing the list of Port instances failed due to I/O problems.
