Package jmri.jmrix.powerline

Class SerialTrafficController

java.lang.Object

jmri.jmrix.AbstractMRTrafficController

jmri.jmrix.powerline.SerialTrafficController

All Implemented Interfaces:

SerialInterface

Direct Known Subclasses:

SpecificTrafficController, SpecificTrafficController, SpecificTrafficController, SpecificTrafficController, SpecificTrafficController

public abstract class SerialTrafficController
extends AbstractMRTrafficController
implements SerialInterface

Converts Stream-based I/O to/from messages. The "SerialInterface" side sends/receives message objects.

The connection to a SerialPortController is via a pair of *Streams, which then carry sequences of characters for transmission. Note that this processing is handled in an independent thread.

This maintains a list of nodes, but doesn't currently do anything with it.

This implementation is complete and can be instantiated, but is not functional. It will be created e.g. when a default object is needed for configuring nodes, etc, during the initial configuration. A subclass must be instantiated to actually communicate with an adapter.

Constructor Detail

SerialTrafficController

Create a new TrafficController instance. Simple implementation.

Method Detail

sendX10Sequence

public void sendX10Sequence(X10Sequence s,
                            SerialListener l)

Send a sequence of X10 messages to an adapter.

Makes them into the local messages and then queues in order.

This is a default, null implementation, which must be overridden in an adapter-specific subclass.

Parameters:

s - sequence to send

l - listener for reply

sendInsteonSequence

public void sendInsteonSequence(InsteonSequence s,
                                SerialListener l)

Send a sequence of Insteon messages to an adapter.

Makes them into the local messages and then queues in order.

This is a default, null implementation, which must be overridden in an adapter-specific subclass.

Parameters:

s - sequence to send

l - listener for reply

sendDmxSequence

public boolean sendDmxSequence(int unitid,
                               byte newStep)

Send a sequence of DMX messages to an adapter.

Makes them into the local messages and then queues in order.

This is a default, null implementation, which must be overridden in an adapter-specific subclass. DMX does work with a sequence, it directly updates the data array

Parameters:

unitid - which light

newStep - new intesity value

Returns:

true on success

getNumberOfIntensitySteps

public int getNumberOfIntensitySteps()

Provide the maximum number of dimming steps available.

Returns:

By default, dimming not available.

getSerialMessage

public SerialMessage getSerialMessage(int length)

Get a message of a specific length for filling in.

This is a default, null implementation, which must be overridden in an adapter-specific subclass.

Parameters:

length - message size

Returns:

null
