  public com.google.common.base.Function<F,T> generate(SourceOfRandomness random, GenerationStatus status)
  
  Description copied from interface: Gen
  
  Generates a value, possibly influenced by a source of randomness and metadata about the generation.
  
  Parameters:
  
  random - source of randomness to be used when generating the value
  
  status - an object that can be used to influence the generated value. For example, generating lists can use the size method to generate lists with a given number of elements.
  
  Returns:
  
  the generated value
- numberOfNeededComponents
