All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`LeafNode`	`getCurrentLeafNode()`	get the current LeafNode after calling the method moveToNextLeaf
`void`	`initShuttle()`	should be called firstly before calling other methods
`void`	`initShuttleFrom(long key)`	Call this instead of initShuttle, if the iterator should start from a bound (upper/lower depending on direction)
`boolean`	`moveToNextLeaf()`
`void`	`remove()`	remove the current visiting LeafNode and its corresponding value container
