Examples of jade.core.Specifier

jade.core.Specifier
This class represent a specifier and collects a name, a className, and an array of arguments. Profile specifiers are used to describe several kinds of complex information when configuring JADE (e.g. MTPs to install, agents to start up, kernel services to activate). The general string format for a specifier is
name:className(separated arglist)
The separated argument list uses a separator character that can be configured when invoking parsing-related utility methods. @author LEAP
