FromStep

All Superinterfaces:

FormalRequirementStep, FromOrUntilStep, IdentifiableRemote, java.rmi.Remote, TptRemote
```
public interface FromStep
extends FromOrUntilStep
```
This FormalRequirementStep yields an interval from the first time the expression becomes true, until the end of the context. The time step where the expression became true is included.

  - setExpression
```
void setExpression(java.lang.String expr)
            throws java.rmi.RemoteException,
                   ApiException
```
    Sets the expression.
    
    Parameters:
    
    expr - the expression from which we are measuring
    
    Throws:
    
    java.rmi.RemoteException - remote communication problem
    
    ApiException - if the expr is null
  - setFollowingIntervalLength
```
void setFollowingIntervalLength(java.lang.String interval)
                         throws java.rmi.RemoteException,
                                ApiException

    Sets a time which extends the interval where the expression is true by the specified duration.
    
    Parameters:
    
    interval - the extending interval
    
    Throws:
    
    java.rmi.RemoteException - remote communication problem
    
    ApiException - if the interval is null
  - getFollowingIntervalLength
```
java.lang.String getFollowingIntervalLength()
                                     throws java.rmi.RemoteException
```
    The time which extends the interval where the expression is true by the specified duration.
