Enum Constant Summary

Enum Constants

Enum Constant and Description
BUFFER Buffers all onNext values until the downstream consumes it.
DROP Drops the most recent onNext value if the downstream can't keep up.
ERROR Signals a MissingBackpressureException in case the downstream can't keep up.
LATEST Keeps only the latest onNext value, overwriting any previous value if the downstream can't keep up.
NONE OnNext events are written without any buffering or dropping.

Enum Constant Detail

NONE

public static final FlowableEmitter.BackpressureMode NONE

OnNext events are written without any buffering or dropping. Downstream has to deal with any overflow.

Useful when one applies one of the custom-parameter onBackpressureXXX operators.

ERROR

public static final FlowableEmitter.BackpressureMode ERROR

Signals a MissingBackpressureException in case the downstream can't keep up.

BUFFER

public static final FlowableEmitter.BackpressureMode BUFFER

Buffers all onNext values until the downstream consumes it.

DROP

public static final FlowableEmitter.BackpressureMode DROP

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

LATEST

public static final FlowableEmitter.BackpressureMode LATEST

Keeps only the latest onNext value, overwriting any previous value if the downstream can't keep up.

Method Detail

values

public static FlowableEmitter.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 (FlowableEmitter.BackpressureMode c : FlowableEmitter.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 FlowableEmitter.BackpressureMode 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
