Enum Constants

Enum Constant and Description
BUFFER Buffer all signals if the downstream can't keep up.
DROP Drop the incoming signal if the downstream is not ready to receive it.
ERROR Signal an IllegalStateException when the downstream can't keep up
IGNORE Completely ignore downstream backpressure requests.
LATEST Downstream will get only the latest signals from upstream.

Enum Constant Detail

IGNORE

public static final FluxSink.OverflowStrategy IGNORE

Completely ignore downstream backpressure requests.

This may yield IllegalStateException when queues get full downstream.

ERROR

public static final FluxSink.OverflowStrategy ERROR

Signal an IllegalStateException when the downstream can't keep up

DROP

public static final FluxSink.OverflowStrategy DROP

Drop the incoming signal if the downstream is not ready to receive it.

LATEST

public static final FluxSink.OverflowStrategy LATEST

Downstream will get only the latest signals from upstream.

BUFFER

public static final FluxSink.OverflowStrategy BUFFER

Buffer all signals if the downstream can't keep up.

Warning! This does unbounded buffering and may lead to OutOfMemoryError.

Method Detail

values

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

Returns:

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

valueOf

public static FluxSink.OverflowStrategy valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
