DDI

All Superinterfaces:

Executable, Initializable

All Known Implementing Classes:

AbstractDDI, CSP, Dataflow, DataflowWithRates, DDF, SDF
```
public interface DDI
extends Executable
```
An interface for domain dependent interpretation. Each instance of CalInterpreter is associated with its own DDI, which performs tasks needed to interpret the actor in a specific domain.
Note: this interface is likely to grow larger as more domains are implemented.

- Method Detail
  - isLegalActor
```
boolean isLegalActor()
```
    Perform static checking on the actor, ensuring its validity in a given domain.
    
    Returns:
    
    True, if the actor is legal.
  - setupActor
```
void setupActor()
```
    Perform any domain dependent setup. This can include hanging various attributes off of the actor, for example, the rate of the input and output ports.
  - getName
```
java.lang.String getName()
```
    Get the name of the domain that this DDI implements.
    
    Returns:
    
    The name of the domain that this DDI implements.
