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 IllegalStateException will be thrown by the Emitter.send method.

      • UNBOUNDED_BUFFER

        public static final OnOverflow.Strategy UNBOUNDED_BUFFER
        Buffers all values until the downstream consumes it. This creates an unbounded buffer so the application may run out of memory if values are continually added faster than they are consumed.
      • 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
        Sends an error signal to the downstream subscriber in the case where it can't keep up. This terminates the reactive stream so no more values will be published.
      • 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
