org.j7m.middleware.application.api.BindingSnapshot
Record Components:
generation - monotonic binding publication generation
sourceRevision - last accepted source revision
candidates - currently eligible bounded candidates
selected - selected concrete reference, empty when unavailable
status - safe availability/lifecycle category
public record BindingSnapshot(long generation, long sourceRevision, List<ObjectRef> candidates, Optional<ObjectRef> selected, String status) extends Record
Immutable typed refresh observation without callback payloads or caller credentials. References are routing evidence and do not grant authority.

  • Method Details

    • 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()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      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. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • generation

      public long generation()
      Returns the value of the generation record component.
      Returns:
      the value of the generation record component

    • sourceRevision

      public long sourceRevision()
      Returns the value of the sourceRevision record component.
      Returns:
      the value of the sourceRevision record component

    • candidates

      public List<ObjectRef> candidates()
      Returns the value of the candidates record component.
      Returns:
      the value of the candidates record component

    • selected

      public Optional<ObjectRef> selected()
      Returns the value of the selected record component.
      Returns:
      the value of the selected record component

    • status
