kotlin coroutine channel
Creating a Channel:
1. Import the necessary dependency: implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.2"
2. Create a channel using Channel()
function: val channel = Channel<Int>()
Sending Elements to the Channel:
1. Use the send
function to send elements to the channel: channel.send(1)
Receiving Elements from the Channel:
1. Use the receive
function to receive elements from the channel: val element = channel.receive()
Closing the Channel:
1. Use the close
function to close the channel: channel.close()
Handling Channel Exceptions:
1. Use try
and catch
blocks to handle ClosedSendChannelException
and ClosedReceiveChannelException
when sending or receiving elements from the channel.
Using Channel in a Coroutine:
1. Create a coroutine using launch
or async
builder.
2. Use send
and receive
functions within the coroutine to send and receive elements from the channel.
Buffering in Channel:
1. Create a buffered channel using Channel(Channel.BUFFERED)
to specify the buffer size.
2. Use offer
instead of send
to send elements to a buffered channel.
Select Expression with Channel:
1. Use the select
expression to receive from multiple channels with a fallback clause.
