• 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.

  • SPECIAL

    public static final BackpressureKind SPECIAL

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

  • UNBOUNDED_IN

    public static final BackpressureKind UNBOUNDED_IN

  • ERROR

    public static final BackpressureKind ERROR

  • NONE

    public static final BackpressureKind NONE

    The operator ignores all kinds of backpressure and may overflow 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
