isClosed

public boolean isClosed()

acquire

public io.netty.util.concurrent.Future<io.netty.channel.Channel> acquire(io.netty.util.concurrent.Promise<io.netty.channel.Channel> promise)

Specified by:

acquire in interface io.netty.channel.pool.ChannelPool

Overrides:

acquire in class io.netty.channel.pool.SimpleChannelPool

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface io.netty.channel.pool.ChannelPool

Specified by:

close in interface Closeable

Overrides:

close in class io.netty.channel.pool.SimpleChannelPool

release

public io.netty.util.concurrent.Future<Void> release(io.netty.channel.Channel channel,
                                                     io.netty.util.concurrent.Promise<Void> promise)

Specified by:

release in interface io.netty.channel.pool.ChannelPool

Overrides:

release in class io.netty.channel.pool.SimpleChannelPool

toString

public String toString()

Overrides:

toString in class Object

offerChannel

protected boolean offerChannel(io.netty.channel.Channel channel)

Offer a Channel back to the internal storage

Maintainers: Implementations of this method must be thread-safe.

Overrides:

offerChannel in class io.netty.channel.pool.SimpleChannelPool

Parameters:

channel - the Channel to return to internal storage

Returns:

true, if the Channel could be added to internal storage; otherwise false

pollChannel

protected io.netty.channel.Channel pollChannel()

Poll a Channel out of internal storage to reuse it

Maintainers: Implementations of this method must be thread-safe and this type ensures thread safety by calling this method serially on a single-threaded EventExecutor. As a result this method need not (and should not) be synchronized.

Overrides:

pollChannel in class io.netty.channel.pool.SimpleChannelPool

Returns:

a value of null, if no Channel is ready to be reused
