OSID - osid.learning.Objective Service Interface Definition

Interface	osid.learning.Objective
Implements	`osid.OsidObject`
Implements	`osid.Federateable`
Description	An `Objective` is a statable learning objective.
Method	hasAssessment
Description	Tests if an assessment is associated with this objective.
Return	`boolean`		`true` if an assessment exists, `false` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	getAssessmentId
Description	Gets the assessment `Id` associated with this learning objective.
Return	`osid.id.Id`		the assessment `Id`
Errors	ILLEGAL_STATE		`hasAssessment()` is `false`
Compliance	`mandatory`		This method must be implemented.
Method	getAssessment
Description	Gets the assessment associated with this learning objective.
Return	`osid.assessment.Assessment`		the assessment
Errors	ILLEGAL_STATE		`hasAssessment()` is `false`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	hasKnowledgeCategory
Description	Tests if this objective has a knowledge dimension.
Return	`boolean`		`true` if a knowledge category exists, `false` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	getKnowledgeCategoryId
Description	Gets the grade `Id` associated with the knowledge dimension.
Return	`osid.id.Id`		the grade `Id`
Errors	ILLEGAL_STATE		`hasKnowledgeCategory()` is `false`
