Enum Constant Detail

SIMPLE

public static final UpdateMode SIMPLE

Simple Update Mode.

In this mode each publish will be a separate update of the topic sending the full value to the server. This allows for normal publishing and also applying patches to JSON topics.

The updates are sent asynchronously to server. If the update fails with transient, retryable error, retry will be performed with last value, set for the topic.

SIMPLE_SYNC

public static final UpdateMode SIMPLE_SYNC

Simple synchronous Update Mode.

In this mode each publish will be a separate update of the topic sending the full value to the server. This allows for normal publishing and also applying patches to JSON topics.

The updates are sent synchronously to server. If the update fails with transient, retryable error, retry will be performed. Only after all retry attempts exhausts, successive update will be published to server. Hence, this mode can be less performant compared to others.

STREAMING

public static final UpdateMode STREAMING

Streaming Update Mode.

In this mode sending updates to the server takes advantage of the Diffusion 'delta' capabilities so that only changes to the value are sent to the server thus significantly reducing bandwidth.

The updates are sent asynchronously to server. If the update fails with transient, retryable error, retry will be performed with last value set to the update stream.

In this mode it is not possible to apply patches to JSON topics.

Method Detail

values

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

Returns:

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

valueOf

public static UpdateMode 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
