deleteAll Method

Delete multiple items from the set, raising onBatchDeleted only once after all items are deleted. This is more efficient than calling delete in a loop when listeners need not be notified of each individual deletion.

deleteAll(items: Iterable<T, any, any>): number

@returns The number of items that were actually deleted (i.e., were present in the set).
