Example usage for javax.management ObjectName getCanonicalName

Introduction

In this page you can find the example usage for javax.management ObjectName getCanonicalName.

Prototype

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.
