Constructs the context for the specified profile.

Parameters:

profile - The profile for which the context should be created.

Method Details

getActiveInstance

public IEntityInstance getActiveInstance(String name)

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:

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

Returns:

The instance that is active for the specified type.

getInferenceDetails

public IInferenceDetails getInferenceDetails(ValueReference attributeReference)

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.
