OSID - osid.financials.ActivityNodeList Service Interface Definition

Interface	osid.financials.ActivityNodeList
Implements	`osid.OsidList`
Used By	`osid.financials.ActivityNode`
Description	Like all `OsidLists`, `ActivityNodeList` provides a means for accessing `ActivityNode` elements sequentially either one at a time or many at a time. Examples: while (anl.hasNext()) { ActivityNode node = anl.getNextActivityNode(); } or while (anl.hasNext()) { ActivityNode[] nodes = anl.getNextActivityNodes(anl.available()); }
Method	getNextActivityNode
Description	Gets the next `ActivityNode` in this list.
Return	`osid.financials.ActivityNode`		the next `ActivityNode` in this list. The `hasNext()` method should be used to test that a next `ActivityNode` 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	getNextActivityNodes
Description	Gets the next set of `ActivityNode` elements in this list. The specified amount must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `ActivityNode` elements requested which must be less than or equal to `available()`
Return	`osid.financials.ActivityNode[]`		an array of `ActivityNode` 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.
