Please read some documentation, such as the lectures available on antlr.org.
These are tree building operators you are talking about.

Someone can explain this ? 

I have some doubts about this piece of code,  for instance 

classDefinition! [AST modifiers]

 what means ! and  [AST modifiers] ? 

{#classDefinition = #(#[CLASS_DEF,"CLASS_DEF"],

 this line i don´t understand !!!!

(piece of code)

 {     classDefinition! [AST modifiers]

        : "class" IDENT

        sc:superClass

        ic:implementsClass

       cb:classBlock

      {#classDefinition = #(#[CLASS_DEF,"CLASS_DEF"],

       modifiers,IDENT,sc,ic,cb);}; 

best regards,
