public String getCanonicalName()

Source Link

Document

Returns the canonical form of the name; that is, a string representation where the properties are sorted in lexical order.

More precisely, the canonical form of the name is a String consisting of the domain part, a colon (:), the canonical key property list, and a pattern indication.

The canonical key property list is the same string as described for #getCanonicalKeyPropertyListString() .

The pattern indication is:

  • empty for an ObjectName that is not a property list pattern;
  • an asterisk for an ObjectName that is a property list pattern with no keys; or
  • a comma and an asterisk (,*) for an ObjectName that is a property list pattern with at least one key.
