OSID - osid.journaling.JournalNodeList Service Interface Definition

Interface	osid.journaling.JournalNodeList
Implements	`osid.OsidList`
Used By	`osid.journaling.JournalNode`
Description	Like all `OsidLists`, `JournalNodeList` provides a means for accessing `JournalNode` elements sequentially either one at a time or many at a time. Examples: while (jnl.hasNext()) { JournalNode node = jnl.getNextJournalNode(); } or while (jnl.hasNext()) { JournalNode[] nodes = jnl.getNextJournalNodes(jnl.available()); }
Method	getNextJournalNode
Description	Gets the next `JournalNode` in this list.

Method	getNextJournalNodes
Description	Gets the next set of `JournalNode` elements in this list. The specified amount must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `JournalNode` elements requested which must be less than or equal to `available()`
Return	`osid.journaling.JournalNode[]`		an array of `JournalNode` elements. The length of the array is less than or equal to the number specified.
