public TDLCausalityInterface(Actor actor,
                             Dependency defaultDependency)
                      throws java.lang.IllegalArgumentException
```
    Construct a causality interface for the specified actor.
    
    Parameters:
    
    actor - The actor for which this is a causality interface. This is required to be an instance of CompositeEntity.
    
    defaultDependency - The default dependency of an output port on an input port.
    
    Throws:
    
    java.lang.IllegalArgumentException - If the actor parameter is not an instance of CompositeEntity.
- Method Detail
  - getMinimumDelay
```
public Dependency getMinimumDelay(IOPort port)
                           throws IllegalActionException
```
    Return the minimum delay for this port. The minimum delay is the minimum model time delay between this port or any equivalent port and a source actor.
    
    Parameters:
    
    port - Port for which the minimum delay should be computed.
    
    Returns:
    
    the minimum delay for the specified port.
    
    Throws:
    
    IllegalActionException - Thrown if minimum delay cannot be computed, because e.g. equivalent ports cannot be computed.
  - wrapup
```
public void wrapup()
```
    Override the base class Clear local variables.
