public interface Entity

An entity is an underlying program "conceptual thing" that can be named by an identifier. The kinds of things include: variables, functions, typedefs, structures, unions, enumerations, enumerators, fields, and labels.

An entity object has some list of declarations associated to it. It begins with no declarations; a declaration is added using method #addDeclaration(DeclarationNode). There are also methods to get the number of declarations and to get the i-th declaration.
