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:

always false since this is a NoopChannelPool

poll

@Nullable
public @Nullable 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:

always null since this is a NoopChannelPool

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:

always false since this is a NoopChannelPool

isOpen

public boolean isOpen()

Description copied from interface: ChannelPool

Return true if a channel can be cached. An 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:

always true since this is a NoopChannelPool

destroy

public void destroy()

Does nothing since this is a NoopChannelPool

Specified by:

destroy in interface ChannelPool

flushPartitions

public void flushPartitions(Predicate<Object> predicate)

Does nothing since this is a NoopChannelPool

Specified by:

flushPartitions in interface ChannelPool

Parameters:

predicate - the predicate

getIdleChannelCountPerHost

public Map<String,Long> getIdleChannelCountPerHost()

Specified by:

getIdleChannelCountPerHost in interface ChannelPool

Returns:

always Collections.emptyMap() since this is a NoopChannelPool
