public static final MqttContext.ErrorHandlingMode DISCONNECT

Disconnect on error.

IGNORE

public static final MqttContext.ErrorHandlingMode IGNORE

Ignore errors, send PUB_ACK if QoS is 1.

SKIP_ACK

public static final MqttContext.ErrorHandlingMode SKIP_ACK

Method Detail

values

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

Returns:

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

valueOf

public static MqttContext.ErrorHandlingMode 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

from

public static MqttContext.ErrorHandlingMode from(String paramValue)

Construct an ErrorHandlingMode object from an MQTT topic property bag parameter value.

Parameters:

paramValue - The parameter value to parse.

Returns:

The parsed ErrorHandlingMode with DEFAULT as default.
