OSID - osid.mapping.path.rules.SignalEnablerList Service Interface Definition

Interface	osid.mapping.path.rules.SignalEnablerList
Implements	`osid.OsidList`
Used By	`osid.mapping.path.rules.SignalEnablerLookupSession`
	`osid.mapping.path.rules.SignalEnablerMapSession`
	`osid.mapping.path.rules.SignalEnablerQuerySession`
	`osid.mapping.path.rules.SignalEnablerRuleLookupSession`
	`osid.mapping.path.rules.SignalEnablerSearchResults`
Description	Like all `OsidLists`, `SignalEnablerList` provides a means for accessing `SignalEnabler` elements sequentially either one at a time or many at a time. Examples: while (sel.hasNext()) { SignalEnabler enabler = sel.getNextSignalEnabler(); } or while (sel.hasNext()) { SignalEnabler[] enablers = sel.getNextSignalEnablers(sel.available()); }
Method	getNextSignalEnabler
Description	Gets the next `SignalEnabler` in this list.
Return	`osid.mapping.path.rules.SignalEnabler`		the next `SignalEnabler` in this list. The `hasNext()` method should be used to test that a next `SignalEnabler` 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	getNextSignalEnablers
Description	Gets the next set of `SignalEnabler` elements in this list. The specified amount must be less than or equal to the return from `available()`.
Parameters	`cardinal`	`n`	the number of `SignalEnabler` elements requested which must be less than or equal to `available()`
Return	`osid.mapping.path.rules.SignalEnabler[]`		an array of `SignalEnabler` 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.
