org.refcodes.serial.LoopbackPortHub

All Implemented Interfaces:

PortHub<LoopbackPort,PortMetrics>

Direct Known Subclasses:

CrossoverLoopbackPortHub

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

The LoopbackPortHub is a plain implementation of a PortHub serving an infinite number of LoopbackPort instances: When calling toPort(String) and the such port is unknown, then it is created (and from then on known).

Constructor Details

LoopbackPortHub

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 Details

ports

public LoopbackPort[] ports()
                     throws IOException

Lists the available ports of the system.

Specified by:

ports in interface PortHub<LoopbackPort,PortMetrics>

Returns:

An array of available Port instances, if there are no ports than an empty array (size 0) is returned.

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.
