Enum Constant Summary

Enum Constants

Enum Constant and Description
ERROR The operator will emit a MissingBackpressureException if the downstream didn't request enough or in time.
FULL The operator fully supports backpressure and may coordinate downstream requests with upstream requests through batching, arbitration or by other means.
NONE The operator ignores all kinds of backpressure and may overflow the downstream.
PASS_THROUGH The backpressure-related requests pass through this operator without change.
SPECIAL The operator performs special backpressure management; see the associated javadoc.
UNBOUNDED_IN The operator requests Long.MAX_VALUE from upstream but respects the backpressure of the downstream.

Method Summary

FULL

public static final BackpressureKind FULL

The operator fully supports backpressure and may coordinate downstream requests with upstream requests through batching, arbitration or by other means.

SPECIAL

public static final BackpressureKind SPECIAL

The operator performs special backpressure management; see the associated javadoc.

UNBOUNDED_IN

public static final BackpressureKind UNBOUNDED_IN

The operator requests Long.MAX_VALUE from upstream but respects the backpressure of the downstream.

Method Detail

values

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

Returns:

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

valueOf

public static BackpressureKind 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
