      public static Identifier of(Object... values)
      Creates a composite identifier, normalizing scalar storage representations. Integral byte, short, and int values compare as longs. Copies the supplied array; components should be immutable. Binary components are unsupported.
      Parameters:
      values - key components in declared identifier-field order
      Returns:
      composite identifier for session lookup
      Throws:
      IllegalArgumentException - if a component is binary

    • values

      public Object[] values()
      Returns a copy of the normalized key component array.
      Returns:
      components in identifier-field order

    • equals

      public boolean equals(Object other)
      Compares normalized components in identifier-field order.
      Overrides:
      equals in class Object
      Parameters:
      other - object to compare
      Returns:
      true if the other identifier has equal components

    • hashCode

      public int hashCode()
      Computes a hash from the normalized key components.
      Overrides:
      hashCode in class Object
      Returns:
      component-based hash code
