Enum Constant Details

AUTOMATIC

public static final FlowControlMode AUTOMATIC

In this mode, Mutation and Deletion events are automatically acknowledged prior to dispatch to the DatabaseChangeListener.

Suitable for listeners whose DatabaseChangeListener.onMutation(Mutation) and DatabaseChangeListener.onDeletion(Deletion) methods either completely process the event (for example, by writing it to disk) or implictly generate backpressure (for example, by writing the event to a bounded blocking queue).

MANUAL

public static final FlowControlMode MANUAL

In this mode, the listener is responsible for calling DocumentChange.flowControlAck() after each Mutation and Deletion event is processed.

NOTE: This mode is not recommended, since it can be difficult to ensure events are acknowledged on all code paths, and failure to ACK can cause the server to stop sending events.

Method Details

values

public static FlowControlMode[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static FlowControlMode valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
