Record Class MapResult.MapResultItem<T>

java.lang.Object
java.lang.Record
software.amazon.lambda.durable.model.MapResult.MapResultItem<T>
Type Parameters:
T - the result type
Record Components:
status - the status of this item
result - the result value, or null if failed/not started
error - the error details, or null if succeeded/not started
Enclosing class:
MapResult<T>
public static record MapResult.MapResultItem<T>(MapResult.MapResultItem.Status status, T result, MapResult.MapError error) extends Record
Represents the outcome of a single item in a map operation.

Each item either succeeds with a result, fails with an error, or was never started. The status field indicates which case applies.

Errors are stored as MapResult.MapError (plain strings) rather than raw Throwable, so they survive serialization across checkpoint-and-replay cycles without requiring AWS SDK-specific Jackson modules.

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()

      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
