protected XNetTrafficController tc

Constructor Detail

XNetThrottleManager

public XNetThrottleManager(XNetSystemConnectionMemo memo)

Constructor.

Parameters:

memo - system connection.

Method Detail

requestThrottleSetup

public void requestThrottleSetup(LocoAddress address,
                                 boolean control)

Request a new throttle object be created for the address, and let the throttle listeners know about it. Abstract member to actually do the work of configuring a new throttle, usually via interaction with the DCC system.

Specified by:

requestThrottleSetup in class AbstractThrottleManager

Parameters:

address - address

control - false - read only.

hasDispatchFunction

public boolean hasDispatchFunction()

XpressNet based systems DO NOT use the Dispatch Function.

Specified by:

hasDispatchFunction in interface ThrottleManager

Overrides:

hasDispatchFunction in class AbstractThrottleManager

Returns:

false always.

singleUse

protected boolean singleUse()

XpressNet based systems can have multiple throttles for the same device.

Does this DCC system allow a Throttle (e.g. an address) to be used by only one user at a time?

Overrides:

singleUse in class AbstractThrottleManager

Returns:

true or false

canBeLongAddress

public boolean canBeLongAddress(int address)

Address 100 and above is a long address.

Specified by:

canBeLongAddress in interface ThrottleManager

Parameters:

address - address number to test

Returns:

true if address can be long; false otherwise

canBeShortAddress

public boolean canBeShortAddress(int address)

Address 99 and below is a short address.

Specified by:

canBeShortAddress in interface ThrottleManager

Parameters:

address - address number to test

Returns:

true if address can be short; false otherwise

addressTypeUnique

public boolean addressTypeUnique()

Are there any ambiguous addresses (short vs long) on this system?

Specified by:

addressTypeUnique in interface ThrottleManager

Returns:

true if ambiguous addresses are not allowed; false otherwise

isLongAddress

protected static boolean isLongAddress(int num)

Local method for deciding short/long address

Parameters:

num - address to examine

Returns:

true if can be long address

supportedSpeedModes

public java.util.EnumSet<SpeedStepMode> supportedSpeedModes()

What speed modes are supported by this system? value should be xor of possible modes specifed by the DccThrottle interface XpressNet supports 14,27,28 and 128 speed step modes

Specified by:

supportedSpeedModes in interface ThrottleManager

Overrides:

supportedSpeedModes in class AbstractThrottleManager

Returns:

an XOR of the possible modes specified in the throttle interface

message

public void message(XNetReply r)

Handle incoming messages for throttles.

Specified by:

message in interface XNetListener

Parameters:

r - The received XNet message. Note that this same object may be presented to multiple users. It should not be modified here.

message

public void message(XNetMessage l)

Listen for the messages to the LI100/LI101.

Specified by:

message in interface XNetListener

Parameters:

l - The received XNet message. Note that this same object may be presented to multiple users. It should not be modified here.

notifyTimeout

public void notifyTimeout(XNetMessage msg)

Handle a timeout notification.

Specified by:

notifyTimeout in interface XNetListener

Parameters:

msg - message which has timed out.

disposeThrottle

public boolean disposeThrottle(DccThrottle t,
                               ThrottleListener l)

Description copied from class: AbstractThrottleManager

Not for general use, see releaseThrottle and dispatchThrottle.

Dispose of object when finished it. This will free up hardware resource

Used for handling certain internal error conditions, where the object still exists but hardware is not associated with it.

After this, further usage of this Throttle object will result in a JmriException.

Specified by:

disposeThrottle in interface ThrottleManager

Overrides:

disposeThrottle in class AbstractThrottleManager

Parameters:

t - Throttle being released

l - Throttle Listener releasing the throttle

Returns:

true if the throttle has been disposed of.
