Enum Constant Summary

Enum Constants

Enum Constant and Description
BUFFER Buffers (unbounded) all onNext calls until the downstream can consume them.
DROP Drops the incoming onNext value if the downstream can't keep up.
ERROR Signals a MissingBackpressureException if the downstream can't keep up.
LATEST Keeps the latest onNext value and overwrites it with newer ones until the downstream can consume it.
NONE No backpressure is applied as the onNext calls pass through the Emitter; note that this may cause MissingBackpressureException or IllegalStateException somewhere downstream.

Enum Constant Detail

NONE

public static final Emitter.BackpressureMode NONE

No backpressure is applied as the onNext calls pass through the Emitter; note that this may cause MissingBackpressureException or IllegalStateException somewhere downstream.

ERROR

public static final Emitter.BackpressureMode ERROR

Signals a MissingBackpressureException if the downstream can't keep up.

BUFFER

public static final Emitter.BackpressureMode BUFFER

Buffers (unbounded) all onNext calls until the downstream can consume them.

DROP

public static final Emitter.BackpressureMode DROP

Drops the incoming onNext value if the downstream can't keep up.

LATEST

public static final Emitter.BackpressureMode LATEST

Keeps the latest onNext value and overwrites it with newer ones until the downstream can consume it.

Method Detail

values

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

Returns:

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

valueOf

public static Emitter.BackpressureMode 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
