Class Event

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.String,​Codec>, Codec
    public class Event
extends Struct
    A representation of a system event. These are generated via the Metadata interfaces and specific to a specific Substrate runtime

    Serialized Form

    • Nested Class Summary

      Nested Classes 
      Modifier and Type Class Description
      static class  Event.EventData
      Wrapper for the actual data that forms part of an Event
      static class  Event.EventIndex
      This follows the same approach as in Method, we have the `[sectionIndex, methodIndex]` pairing that indicates the actual event fired

      • Nested classes/interfaces inherited from class java.util.AbstractMap

        java.util.AbstractMap.SimpleEntry<K extends java.lang.Object,​V extends java.lang.Object>, java.util.AbstractMap.SimpleImmutableEntry<K extends java.lang.Object,​V extends java.lang.Object>
