Class GenGroupGenerator

java.lang.Object
  org.progeeks.tool.gen.BaseDataGenerator
      org.progeeks.tool.gen.GroupMemberGenerator
          org.progeeks.tool.gen.GenGroupGenerator

All Implemented Interfaces:

DataGenerator

public class GenGroupGenerator
extends GroupMemberGenerator

Takes a list of DataGenerators rather than specific objects to return. Selects a generator from the List and invokes generateData on it. This capability is useful if the property to which a GroupMemberGenerator applies can contain values from a set of separate ranges, or from a variety of subclasses, etc.

Important: If any of the member generators allow null to be generated, then the GenGroupGenerator should also allow null or else the isDataValid method may erroneously return false. You can set the nullPercentage to 0.0 if you don't want the main generator to ever actually create a null.
