Enum ChannelState

java.lang.Object

java.lang.Enum<ChannelState>

org.jboss.netty.channel.ChannelState

All Implemented Interfaces:

Serializable, Comparable<ChannelState>

public enum ChannelState
extends Enum<ChannelState>

The current or future state of a Channel.

The state of a Channel is interpreted differently depending on the value of a ChannelStateEvent and the direction of the event in a ChannelPipeline:

Direction	State	Value	Meaning
Upstream	OPEN	true	The channel is open.
Upstream	OPEN	false	The channel is closed.
Upstream	BOUND	SocketAddress	The channel is bound to a local address.
Upstream	BOUND	null	The channel is unbound to a local address.
Upstream	CONNECTED	SocketAddress	The channel is connected to a remote address.
Upstream	CONNECTED	null	The channel is disconnected from a remote address.
Upstream	INTEREST_OPS	an integer	The channel interestOps has been changed.
Downstream	OPEN	true	N/A
Downstream	OPEN	false	Close the channel.
Downstream	BOUND	SocketAddress	Bind the channel to the specified local address.
Downstream	BOUND	null	Unbind the channel from the current local address.
Downstream	CONNECTED	SocketAddress	Connect the channel to the specified remote address.
Downstream	CONNECTED	null	Disconnect the channel from the current remote address.
Downstream	INTEREST_OPS	an integer	Change the interestOps of the channel.

To see how an event is interpreted further, please refer to ChannelEvent.

Method Detail

values

public static ChannelState[] 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 (ChannelState c : ChannelState.values())
    System.out.println(c);

Returns:

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

valueOf

public static ChannelState 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
