DTReceiver()
Construct an empty receiver with no container.
|
DTReceiver(IOPort container)
Construct an empty receiver with the specified container.
|
DTReceiver(IOPort container,
int size)
Construct an empty receiver with the specified container and size.
|
Modifier and Type | Method and Description |
---|---|
(package private) void |
_debugViewReceiverInfo()
For debugging purposes.
|
void |
calculateDeltaTime()
Calculate the constant time increment for this receiver.
|
void |
determineEnds()
Determine the source and destination ports that use this
receiver in their communications.
|
Token |
get()
Remove the first token (the oldest one) from the receiver and
return it.
|
double |
getCurrentTime()
Deprecated.
As of Ptolemy II 4.1, replaced by
getModelTime() |
double |
getDeltaTime()
Return the time interval between tokens for this receiver.
|
Time |
getModelTime()
Return the local time associated with this receiver.
|
TypedIOPort |
getSourcePort()
Return the port that feeds this Receiver
The port returned by this method is precalculated
during the determineEnds() method call.
|
int |
getTokenFlowRate()
Return the token flow rate for this receiver
In DT, the token flow rate has the value
"rate * repetitions"; where 'rate' is the
port rate and 'repetitions' is the firing
count of the actor that contains this
receiver.
|
boolean |
hasToken()
Return true if get() will succeed in returning a token.
|
(package private) void |
initializeLocalTime(Time time)
Initialize the local time to the specified time.
|
void |
put(Token token)
Put a token to the receiver.
|
void |
reset()
Reset this receiver to its initial state, which includes
calling clear() and resetting the current time to 0.0.
