public class SequenceToArray
- extends SDFTransformer
This actor bundles a specified number of input tokens into a single array
and broadcasts the resulting array on all output channels.
The number of tokens to be bundled is specified by the arrayLength
parameter.
This actor is polymorphic. It can accept inputs of any type, as long
as the type does not change, and will produce an array with elements
of the corresponding type.

arrayLength
public PortParameter arrayLength
- The size of the output array. This is an integer that defaults
to 1.
SequenceToArray
public SequenceToArray(CompositeEntity container,
java.lang.String name)
throws NameDuplicationException,
IllegalActionException
- Construct an actor with the given container and name.
- Parameters:
container
- The container.name
- The name of this actor.
- Throws:
IllegalActionException
- If the actor cannot be contained
by the proposed container.
NameDuplicationException
- If the container already has an
actor with this name.
attributeChanged
public void attributeChanged(Attribute attribute)
throws IllegalActionException
- Ensure that the arrayLength parameter is not negative.
- Overrides:
attributeChanged
in class NamedObj
- Parameters:
attribute
- The attribute that has changed.
- Throws:
IllegalActionException
- If the parameters are out of range.
clone
public java.lang.Object clone(Workspace workspace)
throws java.lang.CloneNotSupportedException
- Clone the actor into the specified workspace. This calls the
base class and then creates new ports and parameters.
- Overrides:
clone
in class AtomicActor
- Parameters:
workspace
- The workspace for the new object.
- Returns:
- A new actor.
- Throws:
java.lang.CloneNotSupportedException
- If a derived class contains
an attribute that cannot be cloned.- See Also:
NamedObj.exportMoML(Writer, int, String)
,
NamedObj.setDeferringChangeRequests(boolean)
fire
public void fire()
throws IllegalActionException
- Consume the inputs and produce the output ArrayToken.
- Specified by:
fire
in interface Executable
- Overrides:
fire
in class AtomicActor
- Throws:
IllegalActionException
- If not enough tokens are available.
prefire
public boolean prefire()
throws IllegalActionException
- Return true if the input port has enough tokens for this actor to
fire. The number of tokens required is determined by the
value of the arrayLength parameter.
- Specified by:
prefire
in interface Executable
- Overrides:
prefire
in class SDFTransformer
- Returns:
- boolean True if there are enough tokens at the input port
for this actor to fire.
- Throws:
IllegalActionException
- If the hasToken() query to the
input port throws it.- See Also:
IOPort.hasToken(int, int)
