Enum Constant Detail

STREAMING_SOURCE

public static final ServiceMode STREAMING_SOURCE

Indicates that a service is a streaming source service that consumes streaming data from a back end source and publishes it to Diffusion.

Such a service is implemented by a StreamingSourceHandler.

POLLING_SOURCE

public static final ServiceMode POLLING_SOURCE

Indicates that a service is a polling source service that is periodically polled by the framework for updates which are then published to Diffusion.

Such a service is implemented by a PollingSourceHandler.

SINK

public static final ServiceMode SINK

Indicates that a service is a sink service that consumes data from Diffusion and publishes it to a back end data sink.

Such a service is implemented by a SinkHandler.

HYBRID

public static final ServiceMode HYBRID

Indicates that a service is a hybrid service that both consumes data from Diffusion and publishes data to Diffusion.

This type of service may be used to transform data consumed from Diffusion topics and publish back to different Diffusion topics.

Such a service is implemented by a HybridHandler.

Method Detail

values

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

Returns:

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

valueOf

public static ServiceMode 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
