W302 Tracer Not Recognized

Umple semantic warning issued when a tracer is specified but not recognized

A certain set of MOTL tracers can be specified for use in Umple. Indicating a tracer that is not supported will cause the tracer directive to be ignored, and the Console tracer will be used.

Example

//The tracer used is not recognized,
//the Console tracer will be used
tracer OtherTracer;

class A {
  Integer id;
  
  trace id;
}
// @@@skipphpcompile See issue 596 (PHP tracing causes issues)
      

Load the above code into UmpleOnline

 

Solution to The Above So the Message No Longer Appears

//Using a supported tracer avoids
//the warning
tracer File;

class A {
  Integer id;
  
  trace id;
}
// @@@skipphpcompile See issue 596 (PHP tracing causes issues)
