Method Details

getActiveInstance

public IEntityInstance getActiveInstance(String entityName)
                                  throws UnknownInstanceException,
UnknownEntityException,
CreateInstanceException

Description copied from interface: InferenceContext

This method returns the active instance for the specified type. When no active instance can be found for the specified type, the type is assumed to be a singleton instance. When this method is invoked for a non singleton type without any active instance, the call to the getSingletonInstance will fail due to a CreateInstanceException.

Specified by:

getActiveInstance in interface InferenceContext

Parameters:

entityName - The entity type for which the active instance is requested.

Returns:

The instance that is active for the specified type.

Throws:

UnknownInstanceException - This exception type is raised when no active instance could be found for the specified type.

UnknownEntityException - This exception type is raised when the entity type is unknown.

CreateInstanceException - This type of exception may be raised when a singleton instance could not be created for the specified type.

getInferenceDetails

public IInferenceDetails getInferenceDetails(ValueReference attributeReference)
                                      throws AppException

Description copied from interface: InferenceContext

This method may be used to request detailed inference information for a specific attribute. The details object contains information like which rule inferenced the value, and what other values were used by the rule engine to determine the current result.

Specified by:

getInferenceDetails in interface InferenceContext

Parameters:

attributeReference - The reference to the attribute whose inference information is requested.

Returns:

Object containing detailed information about the value related to the inference process.

Throws:

AppException - This exception is thrown when the inference details could not be retrieved.
