Example 27 with StatelessKieSession

the class RuleExecutor method execute.

/**
 * Validate a concept using drools rules available to this executor.
 * A temporary identifier should be assigned to the concepts or any of it's descriptions and relationships
 * if the component is new and does not yet have an SCTID. The identifier of the component is used to identify invalid content.
 *
 * Passing services in with every invocation of this method allows the implementation to capture content context. For example
 * services relevant to the content branch being worked on.
 * @param ruleSetNames The rule sets to use during validation.
 * @param concepts The concepts to be validated.
 * @param conceptService An implementation of the ConceptService class for use in validation rules.
 * @param descriptionService An implementation of the DescriptionService class for use in validation rules.
 * @param relationshipService An implementation of the RelationshipService class for use in validation rules.
 * @param includePublishedComponents Include the published components of the given concept in results if found to be invalid.
 *                                   Published content will be used during validation regardless just not returned.
 * @param includeInferredRelationships Include the inferred relationships of the given concept during validation and
 *                                     in results if found to be invalid.
 * @return A list of content found to be invalid is returned.
