Method Detail

getModel

public static Model getModel()

Gets the singleton.

By default this class will instantiate a new instance and hold it in a static class variable as the singleton to return for other calls. This behaviour can be changed by setting a system property with key to the name of a class defining a method returning the singleton instance of the model.

Returns:

the singleton instance.

Throws:

ModelError - for unrecoverable model errors.

newModel()

newModel

public static Model newModel()

Creates a new instance of the configured implementation.

The implementation to be used can be controlled via a system property with key set to a class name to be loaded as the implementation.

This method should be used by implementors to retrieve a new instance.

Returns:

a new instance of the configured implementation.

Throws:

ModelError - for unrecoverable model errors.
