Interface DataFactory
- All Known Subinterfaces:
- FertilityFactory, MigrationFactory, MortalityFactory, PopulationSizesFactory
- public interface DataFactory
- extends java.io.Serializable
A superclass interface for the four types of data
factories. Purpose is to allow bundling of these
factories as desired, and/or to allow generic
handling of the factories in methods that do not
require specific references to actual factories.
Also extends java.io.Serializable, so implementing
classes must fulfill that interface too.

Method Summary |
PopulationCharacteristics |
get_characteristics(int category)
Returns a new PopulationCharacteristics object
for the indicated population category. |
PopulationCharacteristics |
get_characteristics(java.lang.String category)
Returns a new PopulationCharacteristics object
for the indicated population category. |
boolean |
ready()
Implementing classes are expected to override this method as a
way to update their characteristics objects if necessary
before each increment of the model. |
get_characteristics
public PopulationCharacteristics get_characteristics(int category)
- Returns a new PopulationCharacteristics object
for the indicated population category.
precondition: category is valid.
get_characteristics
public PopulationCharacteristics get_characteristics(java.lang.String category)
- Returns a new PopulationCharacteristics object
for the indicated population category.
precondition: category is valid.
ready
public boolean ready()
- Implementing classes are expected to override this method as a
way to update their characteristics objects if necessary
before each increment of the model. ModelManager invokes
the method for each DataFactory just prior to incrementing
the Populations.
