OSID - osid.grading.transform.GradeSystemTransform Service Interface Definition

Interface	osid.grading.transform.GradeSystemTransform
Implements	`osid.OsidRule`
Description	A `GradeSystemTransform` represents a translation between two grade systems. The transform is directional such that a translation between the source and target may not equal a translation between the target and the source grade systems.
Method	getSourceGradeSystemId
Description	Gets the source `GradeSystem Id.`
Return	`osid.id.Id`		the source grade system `Id`
Compliance	`mandatory`		This method must be implemented.
Method	getSourceGradeSystem
Description	Gets the source `GradeSystem.`
Return	`osid.grading.GradeSystem`		the source grade system
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getTargetGradeSystemId
Description	Gets the target `GradeSystem Id.`
Return	`osid.id.Id`		the target grade system `Id`
Compliance	`mandatory`		This method must be implemented.
Method	getTargetGradeSystem
Description	Gets the target `GradeSystem.`
Return	`osid.grading.GradeSystem`		the target grade system
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	normalizesInputScores
Description	Tests if this transformation is based on normalization of the input scores.
Return	`boolean`		`true` of a normalization is performed, `false` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	getGradeMaps
Description	Gets any one-to-one mapping of grades.
Return	`osid.grading.transform.GradeMapList`		the grade maps
Compliance	`mandatory`		This method must be implemented.
Method	getGradeSystemTransformRecord
Description	Gets the grade system transform record corresponding to the given `GradeSystemTransform` record `Type.` This method is used to retrieve an object implementing the requested record. The `gradeSystemTransformRecordType` may be the `Type` returned in `getRecordTypes()` or any of its parents in a `Type` hierarchy where `hasRecordType(gradeSystemTransformRecordType)` is `true` .
Parameters	`osid.type.Type`	`gradeSystemTransformRecordType`	the type of the record to retrieve
Return	`osid.grading.transform.records.GradeSystemTransformRecord`		the grade system transform record
Errors	NULL_ARGUMENT		`gradeSystemTransformRecordType` is `null`
	OPERATION_FAILED		unable to complete request
	UNSUPPORTED		`hasRecordType(gradeSystemTransformRecordType)` is `false`
Compliance	`mandatory`		This method must be implemented.
