OSID - osid.process.ProcessNodeList Service Interface Definition

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