Enum Constants

Enum Constant and Description
CLOSED All application data has passed the line and has been confirmed.
CLOSING We've either received or sent a FIN packet indicating that the connection will be terminated.
CONNECTED The connection has been established and application data is able to be sent over the line.
PENDING The socket has been created but there has no action been taken to initiate or receive a connection on it.
RESET Connection has been abruptly closed by a ResetPayload
SYN_RECEIVED We received the initial SYN packet from the remote and have sent the confirmation that we want to establish a connection.
SYN_SENT We sent the initial SYN packet and are awaiting confirmation to establish the connection.

Enum Constant Detail

PENDING

public static final ConnectionState PENDING

The socket has been created but there has no action been taken to initiate or receive a connection on it.

SYN_SENT

public static final ConnectionState SYN_SENT

We sent the initial SYN packet and are awaiting confirmation to establish the connection.

SYN_RECEIVED

public static final ConnectionState SYN_RECEIVED

We received the initial SYN packet from the remote and have sent the confirmation that we want to establish a connection.

CONNECTED

public static final ConnectionState CONNECTED

The connection has been established and application data is able to be sent over the line.

CLOSING

public static final ConnectionState CLOSING

We've either received or sent a FIN packet indicating that the connection will be terminated.

CLOSED

public static final ConnectionState CLOSED

All application data has passed the line and has been confirmed. The connection is now stale.

RESET

public static final ConnectionState RESET

Connection has been abruptly closed by a ResetPayload

Method Detail

values

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

Returns:

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

valueOf

public static ConnectionState 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
