Field Detail

throttles

tc

protected DCCppTrafficController tc

Constructor Detail

DCCppThrottleManager

public DCCppThrottleManager(DCCppSystemConnectionMemo memo)

Constructor.

Parameters:

memo - the memo for the connection this tm will use

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.

Specified by:

requestThrottleSetup in class AbstractThrottleManager

Parameters:

address - address

control - false - read only.

hasDispatchFunction

public boolean hasDispatchFunction()

DCC++ based systems DO NOT use the Dispatch Function (do they?)

Specified by:

hasDispatchFunction in interface ThrottleManager

Overrides:

hasDispatchFunction in class AbstractThrottleManager

Returns:

true if dispatch is possible; false otherwise

singleUse

protected boolean singleUse()

DCC++ 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 128 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 between 1 and 127 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()

There are no ambiguous addresses 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)

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 DCC++ 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(DCCppReply r)

Description copied from interface: DCCppListener

Member function that will be invoked by a DCCppInterface implementation to forward a DCC++ message from the layout.

Specified by:

message in interface DCCppListener

Parameters:

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

message

public void message(DCCppMessage l)

Description copied from interface: DCCppListener

Member function that will be invoked by a DCCppInterface implementation to forward a DCC++ message sent to the layout. Normally, this function will do nothing.

Specified by:

message in interface DCCppListener

Parameters:

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

notifyTimeout

public void notifyTimeout(DCCppMessage msg)

Description copied from interface: DCCppListener

Member function invoked by an DCCppInterface implementation to notify a sender that an outgoing message timed out and was dropped from the queue.

Specified by:

notifyTimeout in interface DCCppListener

Parameters:

msg - the message that timed out.

releaseThrottle

public void releaseThrottle(DccThrottle t,
                            ThrottleListener l)

Description copied from class: AbstractThrottleManager

The specified Throttle Listener has finished using a given throttle and no longer requires access to it.

After releasing the throttle, the manager will perform further checks to see if it is in use by any other listeners or if there are any PropertyChangeListeners attached. If there are no other uses of the throttle then it is disposed of.

Normally, release ends with a call to dispose.

Specified by:

releaseThrottle in interface ThrottleManager

Overrides:

releaseThrottle in class AbstractThrottleManager

Parameters:

t - Throttle being released

l - Throttle Listener releasing the throttle

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.

dispose

public void dispose()

Allow to cleanly release the traffic controller in ThrottleManager Tests

• remove listeners, if any
• stop timers, is any

Specified by:

dispose in interface ThrottleManager

Overrides:

dispose in class AbstractThrottleManager
