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

Interface	osid.grading.transform.GradeMapList
Implements	`osid.OsidList`
Used By	`osid.grading.transform.GradeSystemTransform`
Description	Like all `OsidLists`, `GradeMapList` provides a means for accessing `GradeMap` elements sequentially either one at a time or many at a time. Examples: while (gml.hasNext()) { GradeMap map = gtsl.getNextGradeMap(); } or while (gml.hasNext()) { GradeMap[] maps = gml.getNextGradeMaps(gml.available()); }
Method	getNextGradeMap
Description	Gets the next `GradeMap` in this list.
Return	`osid.grading.transform.GradeMap`		the next `v` in this list. The `hasNext()` method should be used to test that a next `GradeMap` is available before calling this method.
Errors	ILLEGAL_STATE		no more elements available in this list
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getNextGradeMaps
Description	Gets the next set of `GradeMap` elements in this list which must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `GradeMap` elements requested which must be less than or equal to `available()`
Return	`osid.grading.transform.GradeMap[]`		an array of `GradeMap` elements. The length of the array is less than or equal to the number specified.
Errors	ILLEGAL_STATE		no more elements available in this list
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
