Enum Class MiddlewareErrorCode

java.lang.Object
java.lang.Enum<MiddlewareErrorCode>
org.j7m.middleware.api.MiddlewareErrorCode
All Implemented Interfaces:
Serializable, Comparable<MiddlewareErrorCode>, Constable
public enum MiddlewareErrorCode extends Enum<MiddlewareErrorCode>
Stable error codes returned by the middleware public API.

The enum is immutable and thread-safe. Codes are transport-neutral and are used to wrap registry, codec, reflection, RMI, gRPC, and runtime failures before they cross a public API boundary.

  • Method Details

    • values

      public static MiddlewareErrorCode[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static MiddlewareErrorCode valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
