OSID - osid.lexicon.PressNodeList Service Interface Definition

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