Wait for connection to complete before writing with Netty
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have a resilient client based on UptimeClient from Netty's docs (https://netty.io/4.1/xref/io/netty/example/uptime/UptimeClient.html + https://netty.io/4.1/xref/io/netty/example/uptime/UptimeClientHandler.html) which occasionally reconnects due to the IdleStateHandler thinking it's about time. All this is well and good, I want this functionality, but what if I want to write to the channel just as this reconnect is occuring? Being asynchronous, it would just fall through and fail.
Is there a Netty-idiomatic way to chain a write-future after the completion of a possible ongoing reconnect?
This is my write method (in Kotlin):
fun write(message: String) {
channelFuture?.channel()?.writeAndFlush(message)?.addListener { future ->
if (future.isSuccess) {
log.info("Wrote '$message' successfully")
} else {
log.error("Failed to write '$message'")
}
}
}
