public @NotNull CorrelationResult correlate(@NotNull
 @NotNull CorrelationContext correlationContext,
 @NotNull
 @NotNull OperationResult parentResult)

ObjectNotFoundException

Description copied from interface: Correlator

Finds matching focus object (or potentially matching objects) for given resource object or for the pre-focus object. We assume that the correlator is already configured. See CorrelatorFactory.

Specified by:

correlate in interface Correlator

Parameters:

correlationContext - Additional information about the overall context for correlation (e.g. type of focal object`s)

parentResult - Operation result where the method should record its operation

Throws:

SchemaException

ExpressionEvaluationException

CommunicationException

SecurityViolationException

ConfigurationException

ObjectNotFoundException

ExpressionEvaluationException,
CommunicationException,
SecurityViolationException,
ConfigurationException,
ObjectNotFoundException

Description copied from interface: Correlator

Explains how the correlator came to a given candidate owner (and the specific confidence value of it). May not be supported by all correlators. Current support: TODO The `candidateOwner` should be fetched in full, e.g., to be able to access multi-provenance identity and indexed data.
