## Class Description

                    R O O T top level object description

        The TROOT object is the entry point to the ROOT system.
        The single instance of TROOT is accessible via the global gROOT.
        Using the gROOT pointer one has access to basically every object
        created in a ROOT based program. The TROOT object is essentially a
        container of several lists pointing to the main ROOT objects.

        The following lists are accessible from gROOT object:
           gROOT->GetListOfClasses
           gROOT->GetListOfColors
           gROOT->GetListOfTypes
           gROOT->GetListOfGlobals
           gROOT->GetListOfGlobalFunctions
           gROOT->GetListOfFiles
           gROOT->GetListOfMappedFiles
           gROOT->GetListOfSockets
           gROOT->GetListOfSecContexts
           gROOT->GetListOfCanvases
           gROOT->GetListOfStyles
           gROOT->GetListOfFunctions
           gROOT->GetListOfSpecials (for example graphical cuts)
           gROOT->GetListOfGeometries
           gROOT->GetListOfBrowsers
           gROOT->GetListOfCleanups
           gROOT->GetListOfMessageHandlers

       The TROOT class provides also many useful services:
         - Get pointer to an object in any of the lists above
         - Time utilities TROOT::Time

       The ROOT object must be created as a static object. An example
       of a main program creating an interactive version is shown below:

    ---------------------Example of a main program--------------------------------

           #include "TRint.h"

           int main(int argc, char **argv)
           {
              TRint *theApp = new TRint("ROOT example", &argc, argv);

              // Init Intrinsics, build all windows, and enter event loop
              theApp->Run();

              return(0);
           }
    -----------------------End of Main program--------------------------------

~TROOT()

     Clean up and free resources used by ROOT (files, network sockets,
     shared memory segments, etc.).

void AddClass(TClass *cl)

     Add a class to the list and map of classes.

void AddClassGenerator(TClassGenerator *generator)

     Add a class generator.  This generator will be called by TROOT::GetClass
     in case its does not find a loaded rootcint dictionary to request the
     creation of a TClass object.

void Browse(TBrowser *b)

     Add browsable objects to TBrowser.

Bool_t ClassSaved(TClass *cl)

     return class status bit kClassSaved for class cl
     This function is called by the SavePrimitive functions writing
     the C++ code for an object.

TObject* FindObject(const TObject *) const

     Find an object in one Root folder

TObject* FindObject(const char *name) const

     Returns address of a ROOT object if it exists

     If name contains at least one "/" the function calls FindObjectany
     else
     This function looks in the following order in the ROOT lists:
         - List of files
         - List of memory mapped files
         - List of functions
         - List of geometries
         - List of canvases
         - List of styles
         - List of specials
         - List of materials in current geometry
         - List of shapes in current geometry
         - List of matrices in current geometry
         - List of Nodes in current geometry
         - Current Directory in memory
         - Current Directory on file

TObject* FindSpecialObject(const char *name, void *&where)

     Returns address and folder of a ROOT object if it exists

     This function looks in the following order in the ROOT lists:
         - List of files
         - List of memory mapped files
         - List of functions
         - List of geometries
         - List of canvases
         - List of styles
         - List of specials
         - List of materials in current geometry
         - List of shapes in current geometry
         - List of matrices in current geometry
         - List of Nodes in current geometry
         - Current Directory in memory
         - Current Directory on file

TObject* FindObjectAny(const char *name) const

     Return a pointer to the first object with name starting at //root.
     This function scans the list of all folders.
     if no object found in folders, it scans the memory list of all files.

const char* FindObjectClassName(const char *name) const

     Returns class name of a ROOT object including CINT globals.

const char* FindObjectPathName(const TObject *) const

     Return path name of obj somewhere in the //root/... path.
     The function returns the first occurence of the object in the list
     of folders. The returned string points to a static char array in TROOT.
     If this function is called in a loop or recursively, it is the
     user's responsability to copy this string in his area.

TClass* FindSTLClass(const char *name, Bool_t load) const

     return a TClass object corresponding to 'name' assuming it is an STL container.
     In particular we looking for possible alternative name (default template
     parameter, typedefs template arguments, typedefed name).

TClass* GetClass(const char *name, Bool_t load) const

     Return pointer to class with name.

     reading of all currently defined globals from CINT (more expensive).

TGlobal* GetGlobal(const TObject *addr, Bool_t load) const

     Return pointer to global variable with address addr. If load is true
     force reading of all currently defined globals from CINT (more
     expensive).

TFunction* GetGlobalFunction(const char *function, const char *params, Bool_t load)

     Return pointer to global function by name. If params != 0
     it will also resolve overloading. If load is true force reading
     of all currently defined global functions from CINT (more expensive).
     The param string must be of the form: "3189,\"aap\",1.3".

TFunction* GetGlobalFunctionWithPrototype(const char *function, const char *proto, Bool_t load)

     Return pointer to global function by name. If proto != 0
     it will also resolve overloading. If load is true force reading
     of all currently defined global functions from CINT (more expensive).
     The proto string must be of the form: "int, char*, float".

TObject* GetGeometry(const char *name) const

     Return pointer to Geometry with name

TSeqCollection* GetListOfGlobals(Bool_t load)

     Return list containing the TGlobals currently defined.
     Since globals are created and deleted during execution of the
     program, we need to update the list of globals every time we
     execute this method. However, when calling this function in
     a (tight) loop where no interpreter symbols will be created
     you can set load=kFALSE (default).

TSeqCollection* GetListOfGlobalFunctions(Bool_t load)

     Return list containing the TFunctions currently defined.
     Since functions are created and deleted during execution of the
     program, we need to update the list of functions every time we
     execute this method. However, when calling this function in
     a (tight) loop where no interpreter symbols will be created
     you can set load=kFALSE (default).

TSeqCollection* GetListOfTypes(Bool_t load)

     Return list containing all TDataTypes (typedefs) currently defined.
     Since types can be added and removed during execution of the
     program, we need to update the list of types every time we
     execute this method. However, when calling this function in
     a (tight) loop where no new types will be created
     you can set load=kFALSE (default).

void Idle(UInt_t idleTimeInSec, const char *command)

     Execute command when system has been idle for idleTimeInSec seconds.

Int_t IgnoreInclude(const char *fname, const char * /*expandedfname*/)

     Return true if the given include file correspond to a class that has
     been loaded through a compiled dictionnary.

void InitSystem()

     Initialize operating system interface.

void InitThreads()

     Load and initialize thread library.

TClass* LoadClass(const char *classname) const

     Helper function used by TROOT::GetClass().
     This function attempts to load the dictionary for 'classname'
     either from the TClassTable or from the list of generator.

Int_t LoadClass(const char *classname, const char *libname, Bool_t check)

     Check if class "classname" is known to the interpreter. If
     not it will load library "libname". If the library name does
     not start with "lib", "lib" will be prepended and a search will
     be made in the DynamicPath (see .rootrc). If not found a search
     will be made on libname (without "lib" prepended) and if not found
     a direct try of libname will be made (in case it contained an
     absolute path).
     If check is true it will only check if libname exists and is
     readable.
     Returns 0 on successful loading and -1 in case libname does not
     exist or in case of error.

void ls(Option_t *option) const

     To list all objects of the application.
     Loop on all objects created in the ROOT linked lists.
     Objects may be files and windows or any other object directly
     attached to the ROOT linked list.

Int_t LoadMacro(const char *filename, int *error, Bool_t check)

     Load a macro in the interpreter's memory. Equivalent to the command line
     command ".L filename". If the filename has "+" or "++" appended
     the macro will be compiled by ACLiC. The filename must have the format:
     [path/]macro.C[+|++[g|O]].
     The possible error codes are defined by TInterpreter::EErrorCode.
     If check is true it will only check if filename exists and is
     readable.
     Returns 0 on successful loading and -1 in case filename does not
     exist or in case of error.

Long_t Macro(const char *filename, int *error)

     Execute a macro in the interpreter. Equivalent to the command line
     command ".x filename". If the filename has "+" or "++" appended
     the macro will be compiled by ACLiC. The filename must have the format:
     [path/]macro.C[+|++[g|O]][(args)].
     The possible error codes are defined by TInterpreter::EErrorCode.

void Message(Int_t id, const TObject *obj)

     Process message id called by obj

void ProcessLine(const char *line, Int_t *error)

     Process interpreter command via TApplication::ProcessLine().
     On Win32 the line will be processed a-synchronously by sending
     it to the CINT interpreter thread. For explicit synchrounous processing
     use ProcessLineSync(). On non-Win32 platforms there is not difference
     between ProcessLine() and ProcessLineSync().
     The possible error codes are defined by TInterpreter::EErrorCode.  In
     particular, error will equal to TInterpreter::kProcessing until the
     CINT interpreted thread has finished executing the line.

void ProcessLineSync(const char *line, Int_t *error)

     Process interpreter command via TApplication::ProcessLine().
     On Win32 the line will be processed synchronously (i.e. it will
     only return when the CINT interpreter thread has finished executing
     the line). On non-Win32 platforms there is not difference between
     ProcessLine() and ProcessLineSync().
     The possible error codes are defined by TInterpreter::EErrorCode.

Long_t ProcessLineFast(const char *line, Int_t *error)

     Process interpreter command directly via CINT interpreter.
     Only executable statements are allowed (no variable declarations),
     In all other cases use TROOT::ProcessLine().
     The possible error codes are defined by TInterpreter::EErrorCode.

TVirtualProof* Proof(const char *cluster, const char *configfile)

     Start PROOF session on a specific cluster (default is
     "proof://localhost"). The TProof object can be accessed via
     the gProof global. Creating a new TProof object will reset
     the gProof global. For more on PROOF see the TProof ctor.

void RefreshBrowsers()

     Refresh all browsers. Call this method when some command line
     command or script has changed the browser contents. Not needed
     for objects that have the kMustCleanup bit set. Most useful to
     update browsers that show the file system or other objects external
     to the running ROOT session.

void RemoveClass(TClass *oldcl)

     Remove a class from the list and map of classes

void Reset(Option_t *)

     Delete all global interpreter objects created since the last call to Reset

     If option="a" is set reset to startup context (i.e. unload also
     all loaded files, classes, structs, typedefs, etc.).

     This function is typically used at the beginning (or end) of a macro
     to clean the environment.

void SaveContext()

     Save the current interpreter context.

void SetCutClassName(const char *name)

     Set the default graphical cut class name for the graphics editor
     By default the graphics editor creates an instance of a class TCutG.
     This function may be called to specify a different class that MUST
     derive from TCutG

void SetEditorMode(const char *mode)

     Set editor mode

void SetStyle(const char *stylename)

     Change current style to style with name stylename

Int_t DecreaseDirLevel()

Int_t GetDirLevel()

const char* GetMacroPath()

     Get macro search path. Static utility function.

void SetMacroPath(const char *newpath)

     Set or extend the macro search path. Static utility function.
     If newpath=0 or "" reset to value specified in the rootrc file.

Int_t IncreaseDirLevel()

void IndentLevel()

     Functions used by ls() to indent an object hierarchy.

Bool_t Initialized()

Bool_t MemCheck()

void SetDirLevel(Int_t level)

void SetMakeDefCanvas(VoidFuncPtr_t makecanvas)

     Static function used to set the address of the default make canvas method.
     This address is by default initialized to 0.
     It is set as soon as the library containing the TCanvas class is loaded.
