Hi Chen,
The SequenceToArray actor has a length PortParameter.
ArrayToSequence does not have a length PortParameter, the length is part
of the type of the input port.
However, in Ptolemy, ArrayToSequence has an enforceArrayLength
parameter.
http://sisyphus.eecs.berkeley.edu:8079/hudson/job/ptII/javadoc/ptolemy/domains/sdf/lib/ArrayToSequence.html
says:
This actor reads an array at the input and writes the array elements
as a sequence to the output. The parameter /arrayLength/ can be used
to specify the length of arrays that the actor will accept. If the
/enforceArrayLength/ parameter true, then if an input array does not
match /arrayLength/, the fire() method will throw an exception. This
feature is important in domains, such as SDF, that do static
scheduling based on production and consumption rates. For other
domains, such as DE and PN, the /enforceArrayLength/ parameter can be
set to false, in which case the /arrayLength/ parameter will be ignored.

Hi there,
Now I am using the array-to-sequence actor to process an array
contains several string items. How can I specify the arrayLength
argument in this actor automatically?
I tried to add a new input port and pass the length from array-length
actor, but this array-to-sequence actor does not work in this way.
Any suggestion?
Kind regards
Chen
