public class DB extends Transformer implements Rollbackable
The output is never smaller than the value of the min parameter. This makes it easier to plot by limiting the range of output values. If the input is zero or negative, then the output is the value of the min parameter.
The input and output both have type double.

This method should be called instead of the usual prefire(), fire(), postfire() methods when this actor is used in a domain that supports vectorized actors. This leads to more efficient execution.
