MappedMulti

class MappedMulti<P, T>(val parents: List<DeferredValue>, val transform: (List) -> T) : DeferredValue<T>

A DeferredValue that is the result of applying transform to the values of all parents. Inherits the highest sequence number of all parents.

Constructors

MappedMulti

constructor(parents: List<DeferredValue>, transform: (List) -> T)

Properties

parents

val parents: List<DeferredValue>

seqNo

open override val seqNo: Long

The sequence number of this DeferredValue. The sequence number defines the "age" of the value, where a lower sequence number indicates an older value. Sequence numbers are unique for each DeferredValue chain, but are the same for all DeferredValues that are derived from the same source. Use nextSeqNo to generate a new unique sequence number.

transform

val transform: (List) -> T

value

open override val value: T

The possibly lazily initialized value of this DeferredValue. Retrieving this value will initialize it if it hasn't been initialized yet. Once initialized, the value will not change.

Functions

compareTo

open operator override fun compareTo(other: DeferredValue<*>): Int

Compares this DeferredValue with another DeferredValue based on their seqNo. Equivalent to seqNo.compareTo(other.seqNo).
