represents the class or interface declaration. Every interface declaration is accompanied by the additional fact: interfaceT(#id).
Every annotation declaration is accompanied by an interfaceT(#id) and an annotationT(#id) fact.

#id:
the unique ID assigned to this fact.

#parent: compilationUnitT, classDefT, newClassT, blockT, execT

'name':
the class name, without a package. In the case of anonymous classes, a globally unique name: ANONYMOUS$<UN>, where <UN> is a unique number.

[#def_1,…]: methodDefT, fieldDeftT, classDefT, annotationMemberT
list of IDs for other facts representing the methods or fields, and inner classes. These fields and methods are the members (not necessarily public!) of the class.



Note: There is no difference between normal and abstract classes.

class HelloWorld  { //corresponding code line to classDefT
 
   ...
}

classDefT(#id, 'null', 'HelloWorld', [fqn('HelloWorld', '<init>', []), #def_2, #def_3]).

     ast_arg(id,      mult(1,1,no ), id,  [classDefT]), % <-- convention!!!
