## Properties

keyMapper
Link copied to clipboard
open override val keyMapper : SimpleSuspendableMapper < FromKey , ToKey >
onNewValue

open override val onValueRemoved : Flow< FromKey >

This flow must emit data each time when data by Key has been removed with unset/unsetWithValues methods or in any other way
