class TGeoGlobalMagField: public TObject


    TGeoGlobalMagField - Global magnetic field manager. Provides access to
 and owns the actual magnetic field set via SetField(). The field is deleted
 upon destruction of the field manager at the end of ROOT session or
 by calling: TGeoGlobalMagField::Instance()->SetField(0). The previous
 global field is deleted upon replacement with notification.

 The global field manager provides access to the global field via:
   TGeoGlobalMagField::Instance()->GetField()
 One can directly call the Field() method of a field via the global field manager:

   TGeoGlobalMagField::Instance()->Field(x,B)

Function documentation

TGeoGlobalMagField()

 Global field default constructor.

~TGeoGlobalMagField()

 Global field destructor.

void SetField(TVirtualMagField* field)

 Field setter. Deletes previous field if any. Acts only if fLock=kFALSE.

TGeoGlobalMagField * GetInstance()

 Static getter that does not create the object.

TGeoGlobalMagField * Instance()

 Returns always a valid static pointer to the field manager.

void Lock()

 Locks the global magnetic field if this is set. Cannot be unlocked.

TGeoGlobalMagField(const TGeoGlobalMagField& )

TGeoGlobalMagField& operator=(const TGeoGlobalMagField& )

void Unlock()

{fLock = kFALSE;}

TVirtualMagField * GetField() const

 Using SetField() makes a given field global. The field manager owns it from now on.

{return fField;}

Bool_t IsLocked()

{return fLock;}

void Field(const Double_t* x, Double_t* B)

 Inline access to Field() method

{if (fField) fField->Field(x,B);}
