    public abstract class DelayOverflowStrategy
    extends java.lang.Object
    implements java.io.Serializable
    Represents a strategy that decides how to deal with a buffer of time based operator that is full but is about to receive a new element.

    • Method Summary

      All Methods Static Methods Concrete Methods 
      Modifier and Type Method Description
      static DelayOverflowStrategy backpressure()
      If the buffer is full when a new element is available this strategy backpressures the upstream publisher until space becomes available in the buffer.
      static DelayOverflowStrategy dropBuffer()
      If the buffer is full when a new element arrives, drops all the buffered elements to make space for the new element.
      static DelayOverflowStrategy dropHead()
      If the buffer is full when a new element arrives, drops the oldest element from the buffer to make space for the new element.
      static DelayOverflowStrategy dropNew()
      If the buffer is full when a new element arrives, drops the new element.
      static DelayOverflowStrategy dropTail()
      If the buffer is full when a new element arrives, drops the youngest element from the buffer to make space for the new element.
      static DelayOverflowStrategy emitEarly()
      If the buffer is full when a new element is available this strategy send next element downstream without waiting Will backpressure if downstream is not ready.
      static DelayOverflowStrategy fail()
      If the buffer is full when a new element is available this strategy completes the stream with failure.
