Modifier and Type	Method and Description
public final void	close() Implements java.io.Closeable.close. Closes this stream and releases any system resources associated with it.
public final boolean	contains(K key) Implements io.netty.channel.pool.ChannelPoolMap.contains. Returns `true` if a `ChannelPool` exists for the given `key`.
public final P	get(K key) Implements io.netty.channel.pool.ChannelPoolMap.get. Return the `ChannelPool` for the `code`.
public final boolean	isEmpty() Returns `true` if the `AbstractChannelPoolMap` is empty, otherwise `false`.
public final Iterator<Map.Entry<K, P>>	iterator() Implements java.lang.Iterable.iterator. Returns an iterator over elements of type `T`.
protected abstract P	newPool(K key) Called once a new `ChannelPool` needs to be created as non exists yet for the `key`.
private static Future<Void>	poolCloseAsyncIfSupported(ChannelPool the ChannelPool to be closed pool) If the pool implementation supports asynchronous close, then use it to avoid a blocking close call in case the ChannelPoolMap operations are called from an EventLoop.
public final boolean	remove(K key) Remove the `ChannelPool` from this `AbstractChannelPoolMap`.
private Future<Boolean>	removeAsyncIfSupported(K key) Remove the `ChannelPool` from this `AbstractChannelPoolMap`.

Method Detail

close back to summary

close	back to summary
public final void close() Implements java.io.Closeable.close. Doc from java.io.Closeable.close. Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect. As noted in `AutoCloseable#close()`, cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the `Closeable` as closed, prior to throwing the `IOException`. Annotations @Override

public final void close()

Implements java.io.Closeable.close.

Doc from java.io.Closeable.close.

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

As noted in AutoCloseable#close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the Closeable as closed, prior to throwing the IOException.

protected abstract P newPool(K key) Called once a new `ChannelPool` needs to be created as non exists yet for the `key`.

poolCloseAsyncIfSupported	back to summary
private static Future<Void> poolCloseAsyncIfSupported(ChannelPool pool) If the pool implementation supports asynchronous close, then use it to avoid a blocking close call in case the ChannelPoolMap operations are called from an EventLoop. Parameters pool:ChannelPool the ChannelPool to be closed

poolCloseAsyncIfSupported

back to summary

private static Future<Void> poolCloseAsyncIfSupported(ChannelPool pool)

If the pool implementation supports asynchronous close, then use it to avoid a blocking close call in case the ChannelPoolMap operations are called from an EventLoop.

Parameters

pool:ChannelPool: the ChannelPool to be closed

remove	back to summary
public final boolean remove(K key) Remove the `ChannelPool` from this `AbstractChannelPoolMap`. Returns `true` if removed, `false` otherwise. If the removed pool extends `SimpleChannelPool` it will be closed asynchronously to avoid blocking in this method. Please note that `null` keys are not allowed.

removeAsyncIfSupported back to summary

removeAsyncIfSupported	back to summary
private Future<Boolean> removeAsyncIfSupported(K key) Remove the `ChannelPool` from this `AbstractChannelPoolMap`. Returns a future that comletes with a `true` result if the pool has been removed by this call, otherwise the result is `false`. If the removed pool extends `SimpleChannelPool` it will be closed asynchronously to avoid blocking in this method. The returned future will be completed once this asynchronous pool close operation completes.

private Future<Boolean> removeAsyncIfSupported(K key)

Remove the ChannelPool from this AbstractChannelPoolMap. Returns a future that comletes with a true result if the pool has been removed by this call, otherwise the result is false. If the removed pool extends SimpleChannelPool it will be closed asynchronously to avoid blocking in this method. The returned future will be completed once this asynchronous pool close operation completes.

size	back to summary
public final int size() Returns the number of `ChannelPool`s currently in this `AbstractChannelPoolMap`.
