SlotReader

<init>

SlotReader(table: SlotTable)

beginEmpty

fun beginEmpty(): Unit

Begin reporting empty for all calls to next() or get(). beginEmpty() can be nested and must be called with a balanced number of endEmpty()

close

fun close(): Unit

Close the slot reader. After all SlotReaders have been closed the SlotTable a SlotWriter can be created.

endEmpty

fun endEmpty(): Unit

End reporting EMPTY for calls to next and get,

endGroup

fun endGroup(): Unit

End the current group. Must be called after the corresponding startGroup.

endNode

fun endNode(): Unit

End a node

extractKeys

fun extractKeys(): MutableList<KeyInfo>

Extract the keys from this point to the end of the group. The current is left unaffected. Must be called inside a group.

get

fun get(anchor: Anchor): Any?

Get the value stored at anchor.

get

fun get(index: Int): Any?

Get the value stored at index.

groupEnd

fun groupEnd(index: Int): Int

Get location of the end of the group at index.

groupKey

fun groupKey(index: Int): Int

Get the key of the group at index. Will throw an exception if index is not a group start.

groupSize

fun groupSize(index: Int): Int

Get the size of the group at index. Will throw an exception if index is not a group start.

isGroup

fun isGroup(index: Int): Boolean

Determine if the slot at index is the start of a group

isNode

fun isNode(location: Int): Boolean

Determine if the slot at location is a node group. This will throw if the slot at location is not a node.

next

fun next(): Any?

Get the value of the slot at current or EMPTY if at then end of a group. During empty mode this value is always EMPTY which is the value a newly inserted slot.

reposition

fun reposition(value: Int): Unit

skipGroup

fun skipGroup(): Int

Skip a group. Must be called at the start of a group.

skipNode

fun skipNode(): Int

Start a node.

skipToGroupEnd

fun skipToGroupEnd(): Unit

Skip to the end of the current group.

startDataGroup

fun startDataGroup(): Unit

Start a data group.

startGroup

fun startGroup(): Unit

Start a group. Passing an EMPTY as the key will enter the group without validating the key.

startNode

fun startNode(): Unit

Start a node.

toString

fun toString(): String

current

var current: Int

currentEnd

var currentEnd: Int

groupData

val groupData: Any?

Get the data for the current group. Returns null if current is not a group

groupDataKey

val groupDataKey: Any?

Get the data key for the current group. Returns null if the current is not a group.

groupEnd

val groupEnd: Int

Get location the end of the currently started group.

groupKey

val groupKey: Int

Get the key of the current group. Returns 0 if the current is not a group.

groupNode

val groupNode: Any?

Get the node associated with the group if there is one.

groupSize

val groupSize: Int

Get the size of the group at current. Will throw an exception if the isGroup is false.

inEmpty

val inEmpty: Boolean

Determine if a beginEmpty has been called.

isGroup

val isGroup: Boolean

Determine the slot at current is the start of a group and not at the end of the current group.

isGroupEnd

val isGroupEnd: Boolean

Determine if the reader is at the end of a group and an endGroup or endNode is expected.

isNode

val isNode: Boolean

Determine if the slot is start of a node.

nodeIndex

var nodeIndex: Int

parentLocation

val parentLocation: Int

Return the location of the parent group of the current

parentNodes

val parentNodes: Int

Return the number of nodes where emitted into the current group.

parentSlots

val parentSlots: Int

Return the number of slots are in the current group.

table

val table: SlotTable
