classT(#id, #parent, 'name', #paramRef, [#def_1,...])

Represents a class or interface declaration. Every interface declaration is accompanied by the additional fact: interfaceT(#id).

Every classT fact that represents an annotation is accompanied by an interfaceT(#id) and an annotationT(#id) fact for the same #id.

An abstract class is accompanied by an additional fact modifierT(#id, 'abstract').


#id: id
the unique ID assigned to this fact.

#parent: execT, compilationUnitT, classT, newClassT
ID of the element that contains this class declaration.

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

#paramRef: typeParamT
List of the type parameters of the class.

[#def_1,…]: annotationMemberT, classT, fieldT, methodT, constructorT, classInitializerT
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.

Change history
