public class OrderedMerge extends TypedAtomicActor implements Rollbackable
If both input sequences are nondecreasing, then the output sequence will be nondecreasing. Note that if the inputs are not nondecreasing, then the output is rather complex. The key is that in each firing, it produces the smaller of the recorded token and the token it is currently reading.

inputA
The first input port, which accepts any scalar token.
|
Parameter |
inputA_tokenConsumptionRate
The token consumption rate for inputA.
|
TypedIOPort |
inputB

the same type as the first input port.
|
Parameter |
inputB_tokenConsumptionRate
The token consumption rate for inputB.
|
TypedIOPort |
output
The output port, which has the same type as the input ports.
|

OrderedMerge(CompositeEntity container,
java.lang.String name)
Construct an actor with the given container and name.
|

_defaultTypeConstraints()
The output must be greater than or equal to each of both inputs.
|
protected TypedIOPort |
_getNextPort()
Return the port that this actor will read from on the next
invocation of the fire() method.
|
void |
$COMMIT(long timestamp)
Commit changes up to the given timestamp, but not including changes
made at timestamp and afterward.
|
Checkpoint |
$GET$CHECKPOINT()
Get the checkpoint object that monitors this rollbackable object.
|
void |
$RESTORE(long timestamp,
boolean trim)
Restore a previous state to all the private fields of this rollbackable
object.
|
java.lang.Object |
$SET$CHECKPOINT(Checkpoint checkpoint)
Set the checkpoint object of this rollbackable object.
|
java.lang.Object |
clone(Workspace workspace)
Clone the actor into the specified workspace.
|
void |
fire()
Read one token from the port that did not provide the recorded
token (or inputA, on the first firing), and output the
smaller of the recorded token or the newly read token.
|
void |
initialize()
Initialize this actor to indicate that no token is recorded.
|
boolean |
postfire()
Commit the recorded token.
