public class VectorDisassembler
- extends Transformer
An actor that disassembles a DoubleMatrixToken to a multiport output.
On each firing, read one column or row vector (i.e. a
DoubleMatrixToken with one column or row) from the input port and
send out individual DoubleTokens to each channel of the output
port. If the width of the output port (say, n) is less than
the number of rows (say, m) in the input token, then the first
n elements in the vector will be sent, and the remaining tokens are
discarded. If n is greater than m, then the last
n-m channels of the output port will never send tokens out.
This class throws an exception if the input is not a column vector.
For sequential domains like SDF, the combination of
domains.sdf.lib.MatrixToDouble and a Distributor is equivalent to this
actor. However, that combination will not work in CT, so we need this
actor.

fire()
If there is a token at the input, read one column or row vector
(i.e. a DoubleMatrixToken with one column or row) from the
input port, and for each channel i of the output port,
send send the ith element of this column or row vector to this
channel. |

VectorDisassembler
public VectorDisassembler(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 this actor cannot be contained
by the proposed container.
NameDuplicationException - If the container already has an
actor with this name.
fire
public void fire()
throws IllegalActionException
- If there is a token at the input, read one column or row vector
(i.e. a DoubleMatrixToken with one column or row) from the
input port, and for each channel i of the output port,
send send the ith element of this column or row vector to this
channel. Otherwise, do nothing.
Note: The output tokens are copies of the corresponding
elements in the input token.
- Specified by:
fire in interface Executable- Overrides:
fire in class AtomicActor
- Throws:
IllegalActionException - If there is no director, or
the input token has more than one columns and rows.
