Enum Constant Detail

DISCONNECTED

public static final MqttClientState DISCONNECTED

The client is disconnected.

CONNECTING

public static final MqttClientState CONNECTING

The client is connecting.

This means the client was DISCONNECTED, a Connect message is sent, but the ConnAck message is not received yet.

CONNECTED

public static final MqttClientState CONNECTED

The client is connected.

DISCONNECTED_RECONNECT

public static final MqttClientState DISCONNECTED_RECONNECT

The client is disconnected but will reconnect.

CONNECTING_RECONNECT

public static final MqttClientState CONNECTING_RECONNECT

The client is reconnecting.

This means the client was DISCONNECTED_RECONNECT, a Connect message is sent, but the ConnAck message is not received yet.

Method Detail

values

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

Returns:

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

valueOf

public static MqttClientState 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

isConnected

public boolean isConnected()

Returns:

whether the client is connected.

isConnectedOrReconnect

public boolean isConnectedOrReconnect()

Returns:

whether the client is connected or will reconnect.
