Class SampleDelay

• public class SampleDelay
• extends SDFTransformer

This actor outputs a set of initial tokens during the initialize() method, and subsequently passes the input tokens to the output. It is used to break dependency cycles in directed loops of SDF models. This actor declares an initial production parameter in its output port that is used by the SDF scheduler to properly schedule the model, and the initial outputs permit the computation to get started. The default value for the initialOutputs parameter causes a single integer token with value zero to be produced in initialize().

initialOutputs

public VisualSim.data.expr.Parameter initialOutputs

• The values that will be produced in the initialize method. This parameter must contain an ArrayToken. It defaults to contain a single zero-valued integer token. Changes to this parameter after initialize() has been invoked are ignored until the next execution of the model.
