Method Detail

values

public static NoopChannelPool[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NoopChannelPool c : NoopChannelPool.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NoopChannelPool valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

offer

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

Description copied from interface: ChannelPool

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)

Description copied from interface: ChannelPool

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)

Description copied from interface: ChannelPool

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()

Description copied from interface: ChannelPool

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()

Description copied from interface: ChannelPool

Destroy all channels that has been cached by this instance.

Specified by:

destroy in interface ChannelPool

flushPartitions

public void flushPartitions(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.
