FilteredList

class FilteredList<E>(val source: ObservableList<E>, filter: (E) -> Boolean? = null) : ObservableList<E>

Provides a filtered view of an underlying ObservableList. Changes to this list affect the underlying list, but their effects may not be visible once applied due to filter.

Parameters

filter

to apply to source

Constructors

FilteredList

constructor(source: ObservableList<E>, filter: (E) -> Boolean? = null)

Properties

changed

open override val changed: ListObservers<ObservableList<E>, E>

Notifies of changes to the list

filter

var filter: (E) -> Boolean?

The filter applied to source

size

open override val size: Int

source

val source: ObservableList<E>

list underlying this one

Functions

add

open override fun add(element: E): Boolean

open override fun add(index: Int, element: E)

batch

open override fun <T> batch(block: MutableList<E>.() -> T): T

Runs the operations within block and then applies them all to the list as a single operation. This reduces the set of events that would normally trigger if these operations were done sequentially.

clear

open override fun clear()

contains

open operator override fun contains(element: E): Boolean

equals

open operator override fun equals(other: Any?): Boolean

get

open operator override fun get(index: Int): E

hashCode

open override fun hashCode(): Int

indexOf

open override fun indexOf(element: E): Int

isEmpty

open override fun isEmpty(): Boolean

iterator

open operator override fun iterator(): MutableIterator<E>

lastIndexOf

open override fun lastIndexOf(element: E): Int

minusAssign

open operator override fun minusAssign(element: E)

Removes element from the list

move

open override fun move(element: E, to: Int): Boolean

Moves element to a new index.

notifyChanged

open override fun notifyChanged(index: Int)

Explicitly trigger a diff that shows the element at index being deleted and re-added. This is useful for cases where the elements in the list are mutable and a change has happened to one that would normally not result in a call to changed (which only notifies of membership changes.
