OSID - osid.commenting.BookNodeList Service Interface Definition

Interface	osid.commenting.BookNodeList
Implements	`osid.OsidList`
Used By	`osid.commenting.BookNode`
Description	Like all `OsidLists`, `BookNodeList` provides a means for accessing `BookNode` elements sequentially either one at a time or many at a time. Examples: while (bnl.hasNext()) { BookNode node = bnl.getNextBookNode(); } or while (bnl.hasNext()) { BookNode[] nodes = bnl.getNextBookNodes(bnl.available()); }
Method	getNextBookNode
Description	Gets the next `BookNode` in this list.
Return	`osid.commenting.BookNode`		the next `BookNode` in this list. The `hasNext()` method should be used to test that a next `BookNode` is available before calling this method.

Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getNextBookNodes
Description	Gets the next set of `BookNode` elements in this list. The specified amount must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `BookNode` elements requested which must be less than or equal to `available()`
Return	`osid.commenting.BookNode[]`		an array of `BookNode` elements. The length of the array is less than or equal to the number specified.
