Enum OnOverflow.Strategy

    • Enum Constant Detail

      • BUFFER

        public static final OnOverflow.Strategy BUFFER
        Buffers all values until the downstream consumes it. This creates a buffer with the size specified by OnOverflow.bufferSize() if present. Otherwise, the size will be the value of the config property mp.messaging.emitter.default-buffer-size. If the buffer is full, an error will be propagated.
      • UNBOUNDED_BUFFER

        public static final OnOverflow.Strategy UNBOUNDED_BUFFER
        Buffers all values until the downstream consumes it. This creates an unbound buffer. If the buffer is full, the application will die of OutOfMemory.
      • DROP

        public static final OnOverflow.Strategy DROP
        Drops the most recent value if the downstream can't keep up. It means that new value emitted by the upstream are ignored.
      • FAIL

        public static final OnOverflow.Strategy FAIL
        Propagates a failure in case the downstream can't keep up.
      • LATEST

        public static final OnOverflow.Strategy LATEST
        Keeps only the latest value, dropping any previous value if the downstream can't keep up.
      • NONE

        public static final OnOverflow.Strategy NONE
        The values are propagated without any back pressure strategy. It's the responsibility from the downstream to implement a strategy to deal with overflow.

      • values

        public static OnOverflow.Strategy[] 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 (OnOverflow.Strategy c : OnOverflow.Strategy.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static OnOverflow.Strategy 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
