Method Detail

offer

public boolean offer(io.netty.channel.Channel channel,
                     Object partitionKey)

Add a channel to the pool

Specified by:

offer in interface ChannelPool

Parameters:

channel - an I/O channel

partitionKey - a key used to retrieve the cached channel

Returns:

true if added.

poll

public io.netty.channel.Channel poll(Object partitionKey)

Remove the channel associated with the uri.

Specified by:

poll in interface ChannelPool

Parameters:

partitionKey - the partition used when invoking offer

Returns:

the channel associated with the uri

removeAll

public boolean removeAll(io.netty.channel.Channel channel)

Remove all channels from the cache. A channel might have been associated with several uri.

Specified by:

removeAll in interface ChannelPool

Parameters:

channel - a channel

Returns:

the true if the channel has been removed

isOpen

public boolean isOpen()

Return true if a channel can be cached. A implementation can decide based on some rules to allow caching Calling this method is equivalent of checking the returned value of ChannelPool.offer(Channel, Object)

Specified by:

isOpen in interface ChannelPool

Returns:

true if a channel can be cached.

destroy

public void destroy()

Destroy all channels that has been cached by this instance.

Specified by:

destroy in interface ChannelPool

flushPartitions

public void flushPartitions(java.util.function.Predicate<Object> predicate)

Description copied from interface: ChannelPool

Flush partitions based on a predicate

Specified by:

flushPartitions in interface ChannelPool

Parameters:

predicate - the predicate

getIdleChannelCountPerHost

public Map<String,Long> getIdleChannelCountPerHost()

Specified by:

getIdleChannelCountPerHost in interface ChannelPool

Returns:

The number of idle channels per host.
