public class Repeat
- extends SDFTransformer
An actor that repeats a block of input tokens the specified number of times
on the output. On each firing, it reads blockSize tokens
and repeats each block numberOfTimes times
on the output. Note that this causes a sample rate increase by
a factor of numberOfTimes,
and hence affects the number of invocations of downstream actors.

numberOfTimes
public Parameter numberOfTimes
- The repetition factor. It is of type integer and has a default
value of 2. It must be greater than zero.
blockSize
public Parameter blockSize
- The number of tokens in a block. It is of type integer and has a
default value of 1. It must be greater than zero.
Repeat
public Repeat(CompositeEntity container,
java.lang.String name)
throws IllegalActionException,
NameDuplicationException
- Construct an actor in the specified container with the specified
name.
- Parameters:
container - The container.name - The name of this Repeat actor within the container.
- Throws:
IllegalActionException - If the actor cannot be contained
by the proposed container.
NameDuplicationException - If the name coincides with
an actor already in the container.
attributeChanged
public void attributeChanged(Attribute attribute)
throws IllegalActionException
- Ensure that the numberOfTimes parameter and the blockSize
parameter are both positive.
- Overrides:
attributeChanged in class NamedObj
- Parameters:
attribute - The attribute that has changed.
- Throws:
IllegalActionException - If the parameters are out of range.
fire
public void fire()
throws IllegalActionException
- Consume blockSize input tokens from the input port.
Produce blockSize*numberOfTimes
tokens on the output port, consisting of numberOfTimes
repetitions of the input. For example, if blockSize = 3 and
numberOfTimes = 2, then on the following input:
1 2 3 4 5 6
two invocations of this method will send the following output:
1 2 3 1 2 3 4 5 6 4 5 6
- Specified by:
fire in interface Executable- Overrides:
fire in class AtomicActor
- Throws:
IllegalActionException - If there is no director.
