OSID - osid.assessment.AssessmentSession Service Interface Definition

Interface	osid.assessment.AssessmentSession
Implements	`osid.OsidSession`
Description	This session is used to take an assessment. The assessment associated with this session represents the "assessment taken" by an `Agent.` This session may be created using an `AssessmentOffered` `Id` retrieved from an assessment bank, and instantiating this session represents the transaction of taking an assessment. Resuming an assessment, if permitted, is performed through instantiating this session with the `AssessmentTaken` `Id.` `Assessment Items` are accessed via the `Question` interface. A `Question` `Id` is the same as the `Item` Id. This session manages the flow of control for the assessment taking process. It allows for two types of processes: synchronous response: Each consecutive question is only available after the previous item was submitted or skipped. asynchronous response: Questions may be accessed independently of response submission. It may be the case that it is allowed to suspend and resume an assessment. `canSuspend()` indicates the availability of this feature. `finished()` indicates the assessment is complete. This session is used in the context of an `AssessmentSection.` An assessment with no sections defined is assumed to have a single default section that maps to the entire assessment.
Method	getBankId
Description	Gets the `Bank` `Id` associated with this session.
Return	`osid.id.Id`		the `Bank Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getBank
Description	Gets the `Bank` associated with this session.
Return	`osid.assessment.Bank`		the `Bank` associated with this session
Errors	OPERATION_FAILED		unable to complete request

Method	canTakeAssessments
Description	Tests if this user can take this assessment section. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a `PERMISSION_DENIED.` This is intended as a hint to an application that may opt not to offer assessment operations to unauthorized users.
Return	`boolean`		`false` if assessment methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	hasAssessmentBegun
Description	Tests if this assessment has started. An assessment begins from the designated start time if a start time is defined. If no start time is defined the assessment may begin at any time. Assessment sections cannot be accessed if the return for this method is `false.`
Parameters	`osid.id.Id`	`assessmentTakenId`	`Id` of the `AssessmentTaken`
Return	`boolean`		`true` if this assessment has begun, `false` otherwise
Errors	NOT_FOUND		`assessmentTakenId` is not found
	NULL_ARGUMENT		`assessmentTakenId` is `null`
	OPERATION_FAILED		unable to complete request

Compliance	`mandatory`		This method must be implemented.
Method	isAssessmentOver
Description	Tests if this assessment is over. An assessment is over if `finishedAssessment()` is invoked or the designated finish time has expired.
Parameters	`osid.id.Id`	`assessmentTakenId`	`Id` of the `AssessmentTaken`
Return	`boolean`		`true` if this assessment is over, `false` otherwise

Method	requiresSynchronousSections
Description	Tests if synchronous sections are required. This method should be checked to determine if all sections are available when requested, or the next sections becomes available only after the previous section is complete. There are two methods for retrieving sections. One is using the built-in hasNextSection() and getNextSection() methods. In synchronous mode, hasNextSection() is false until the current section is completed. In asynchronous mode, `hasNextSection()` returns true until the end of the assessment. `AssessmentSections` may also be accessed via an `AssessmentSectionList.` If syncronous sections are required, `AssessmentSectionList.available() == 0` and `AssessmentSectionList.getNextQuestion()` blocks until the section is complete. `AssessmentSectionList.hasNext()` is always true until the end of the assessment is reached.
Parameters	`osid.id.Id`	`assessmentTakenId`	`Id` of the `AssessmentTaken`
