class TGeoBranchArray: public TObject


 TGeoBranchArray - An array of daughter indices making a geometry path.
   Can be used to backup/restore a state. To setup an object of this type,
 one should use:
   TGeoBranchArray *array = new TGeoBranchArray(level);
   array->InitFromNavigator(nav); (To initialize from current navigator state)
 The navigator can be updated to reflect this path array:
   array->UpdateNavigator();

Function documentation

TGeoBranchArray(Int_t level)
 Constructor. Alocates the array with a size given by level.
TGeoBranchArray * MakeInstance(size_t maxlevel)
 Make an instance of the class which allocates the node array. To be
 released using ReleaseInstance. If addr is non-zero, the user promised that
 addr contains at least that many bytes:  size_t needed = SizeOf(maxlevel);
TGeoBranchArray * MakeInstanceAt(size_t maxlevel, void* addr)
 Make an instance of the class which allocates the node array. To be
 released using ReleaseInstance. If addr is non-zero, the user promised that
 addr contains at least that many bytes:  size_t needed = SizeOf(maxlevel);
TGeoBranchArray * MakeCopy(const TGeoBranchArray& other)
 Make a copy of a branch array at the location (if indicated)
TGeoBranchArray * MakeCopyAt(const TGeoBranchArray& other, void* addr)
 Make a copy of a branch array at the location (if indicated)
void CopyTo(TGeoBranchArray* dest)
 Raw memcpy of the branch array content to an existing destination.
void ReleaseInstance(TGeoBranchArray* obj)
 Releases the space allocated for the object
void UpdateArray(size_t nobj)
 Updates the internal addresses for n contiguous objects which have the same
 fMaxLevel
 Updates the internal addresses for n contiguous objects which have the same fMaxLevel
TGeoBranchArray(const TGeoBranchArray& )
 Copy constructor. Not callable anymore. Use TGeoBranchArray::MakeCopy instead
TGeoBranchArray& operator=(const TGeoBranchArray& )
 Assignment. Not valid anymore. Use TGeoBranchArray::MakeCopy instead
void AddLevel(Int_t dindex)
 Add and extra daughter to the current path array. No validity check performed !
Long64_t BinarySearch(Long64_t n, const TGeoBranchArray** array, TGeoBranchArray* value)
 Binary search in an array of n pointers to branch arrays, to locate value.
 Returns element index or index of nearest element smaller than value
Int_t Compare(const TObject* obj) const
 Compare with other object of same type. Returns -1 if this is smaller (first
 smaller array value prevails), 0 if equal (size and values) and 1 if this is
 larger.
void CleanMatrix()
 Garbage collect the stored matrix.
void Init(TGeoNode** branch, TGeoMatrix* global, Int_t level)
 Init the branch array from an array of nodes, the global matrix for the path and
 the level.
void InitFromNavigator(TGeoNavigator* nav)
 Init the branch array from current navigator state.
void GetPath(TString& path) const
 Fill path pointed by the array.
void Print(Option_t* option = "") const
 Print branch information
void Sort(Int_t n, TGeoBranchArray** array, Int_t* index, Bool_t down = kTRUE)
 Sorting of an array of branch array pointers.
void UpdateNavigator(TGeoNavigator* nav) const
 Update the navigator to reflect the branch.
   nav->CdTop();
TGeoBranchArray(Int_t level)

 Equivalent of sizeof function
{ return (sizeof(TGeoBranchArray)+sizeof(TGeoBranchArray*)*(maxlevel)); }
size_t SizeOfInstance(size_t maxlevel)
 Equivalent of sizeof function
{ return (sizeof(TGeoBranchArray)+sizeof(TGeoBranchArray*)*(maxlevel)); }
size_t SizeOf() const
{ return (sizeof(TGeoBranchArray)+sizeof(TGeoBranchArray*)*(fMaxLevel)); }

 The data start should point to the address of the first data member,
 after the virtual table
{return (void*)&fLevel;}
size_t DataSize() const
 The actual size of the data for an instance, excluding the virtual table
{return SizeOf()-size_t(&fLevel)+(size_t)this;}
virtual ~TGeoBranchArray()
 Destructor. Release instance to be called instead
{}
TGeoNode ** GetArray() const
{return fArray;}
size_t GetLevel() const
{return fLevel;}
size_t GetMaxLevel() const
{return fMaxLevel;}

{return fArray[level];}
