ConflatedChannel
open class ConflatedChannel<E> : AbstractChannel<E>
Channel that buffers at most one element and conflates all subsequent send
and offer
invocations,
so that the receiver always gets the most recently sent element.
Backtosend sent elements are conflated – only the the most recently sent element is received,
while previously sent elements are lost.
Sender to this channel never suspends and offer always returns true
.
This channel is created by Channel(Channel.CONFLATED)
factory function invocation.
This implementation is fully lockfree.

Inherited Properties
val isClosedForReceive: Boolean Returns 

val isEmpty: Boolean Returns 

val onReceive: SelectClause1<E> Clause for select expression of receive suspending function that selects with the element that is received from the channel. The select invocation fails with exception if the channel isClosedForReceive (see close for details). 

val onReceiveOrNull: SelectClause1<E?> Clause for select expression of receiveOrNull suspending function that selects with the element that
is received from the channel or selects with 
Inherited Functions
Cancels reception of remaining elements from this channel. This function closes the channel with
the specified cause (unless it was already closed) and removes all buffered sent elements from it.

open fun cleanupSendQueueOnCancel(): Unit 

fun iterator(): ChannelIterator<E> Returns new iterator to receive elements from this channels using 

fun poll(): E? Retrieves and removes the element from this channel, or returns 

suspend fun receive(): E Retrieves and removes the element from this channel suspending the caller while this channel isEmpty or throws ClosedReceiveChannelException if the channel isClosedForReceive. If the channel was closed because of the exception, it is called a failed channel and this function throws the original close cause exception.
