    Specified by:
    
    onId in interface Listener
    
    Parameters:
    name - the location name.
  - onMacro
```
public void onMacro(String id,

    Some text to inject directly into the listener output without parsing it. For example a HTML macro could inject directly some HTML entered by the user into the rendered HTML output. Note that it's not recommended to use this event in most cases since it can lead to invalid content being generated and in addition most listener implementations will not understand the injected text and will just ignore it.
    
    Specified by:
    
    onRawText in interface Listener
    
    Parameters:
    rawContent - the text to inject
    syntax - the syntax in which the text is written. This is useful so that listener implementations can decide whether they can handle direct inject for that syntax
