    Description copied from interface: IPerformanceTracer
    
    Include trace information from another instance as part of active task. Might come handy to overcome limitations of single-threaded implementation (e.g. generator's main thread with a 'global' tracer, and individual transformation threads reporting into own trace, with results merged).
    
    Specified by:
    
    push in interface IPerformanceTracer
    
    Parameters:
    
    other - not null
  - pop
```
public void pop()
```
    Specified by:
    
    pop in interface IPerformanceTracer
  - report
```
public String report(String... separate)
```
    Specified by:
    
    report in interface IPerformanceTracer
    
    Parameters:
    
    separate - name of tasks not to get merged with other and reported individually
    
    Returns:
    
    multi-line report text
  - addText
```
public void addText(String s)
```
    Specified by:
    
    addText in interface IPerformanceTracer
