MutableEventIterator

interface MutableEventIterator : EventIterator, MutableListIterator<Event>

A mutable variation of EventIterator, which may be used to mutate an underlying log of events.

Functions

abstract fun add(element: Event)

abstract fun add( seqno: SequenceNumber, site: SiteIdentifier, event: ByteArray, from: Int = 0, until: Int = event.size)

Adds an event at the current implicit cursor position, and moves the cursor after the inserted element.

hasNext

abstract operator override fun hasNext(): Boolean

hasPrevious

abstract fun hasPrevious(): Boolean

moveNext

abstract fun moveNext()

Moves the EventIterator to the next event, without allocations.

movePrevious

abstract fun movePrevious()

Moves the EventIterator to the previous event, without allocations.

abstract operator override fun next(): Event

nextIndex

abstract fun nextIndex(): Int

abstract fun previous(): Event

previousIndex

abstract fun previousIndex(): Int

remove

abstract override fun remove()

set

abstract fun set(element: Event)
