TDictionary Class Referenceabstract

This class defines an abstract interface that must be implemented by all classes that contain dictionary information.

The dictionary is defined by the following classes:

TDataType (typedef definitions)
TGlobal (global variables)
TGlobalFunc (global functions)
TClass (classes)
TBaseClass (base classes)
TDataMember (class datamembers)
TMethod (class methods)
TMethodArg (method arguments)
Each class (see TClass) has a linked list of its base class(es).
Definition TBaseClass.h:33
TClass instances represent classes, structs and namespaces in the ROOT type system.
Definition TClass.h:80
All ROOT classes may have RTTI (run time type identification) support added.
Definition TDataMember.h:31
Basic data type descriptor (datatype information is obtained from CINT).
Definition TDataType.h:44
Global variables class (global variables are obtained from CINT).
Definition TGlobal.h:28
Each ROOT method (see TMethod) has a linked list of its arguments.
Definition TMethodArg.h:36
Each ROOT class (see TClass) has a linked list of methods.
Definition TMethod.h:38

All the above classes implement the TDictionary abstract interface. Note: the indentation shows aggregation not inheritance.

TMethodCall (method call environment)
Method or function calling interface.
Definition TMethodCall.h:37
