Detailed Description

stl-iterator for the histogram manager

Author

Markus Fasel marku.nosp@m.s.fa.nosp@m.sel@c.nosp@m.ern..nosp@m.ch, Lawrence Berkeley National Laboratory

stl-type iterator for the histogram manager. Iterating over primary content of the histogram manager. In case histograms are organized in groups, the primary content will be histogram groups, with the data structure THashList. The iterator is implemented as bidirectional iterator, providing forward and backward iteration.

Member Enumeration Documentation

enum THistManager::iterator::THMIDirection_t

Direction for the iteration.

Switch for the firection of the iteration. Currently the iterator is implemented as bi-directional iterator, providing only forward and backward iteration.

Enumerator
kTHMIforward	Forward iteration.
kTHMIbackward	Backward iteration.

Definition at line 72 of file THistManager.h.

Constructor & Destructor Documentation

THistManager::iterator::iterator	(	const THistManager *	hmgr,
		Int_t	currentpos,
		THMIDirection_t	dir = kTHMIforward
	)

Constructor. Initializing the histogram manager to be iterated over, the starting position for the iteration, and the direction of the iteration.

Parameters

[in]	hmgr	Histogram manager to be iterated over, containing the data
[in]	currentpos	Starting position for the iteration
[in]	dir	Direction of the iteration

Member Function Documentation

bool THistManager::iterator::operator!=

(

const iterator &

aIter

)

const

Comparison operator for unequalness. The comparison is performed based on the current position of the iterator.

Parameters

[in]

other

iterator to compare to

Returns

True if the iterators are not equal

Definition at line 634 of file THistManager.cxx.

TObject * THistManager::iterator::operator*

(

)

const

Dereferncing operator. Providing access to the object connected to the current state of the iterator. Objects might be histograms or THashLists in case of wheter groups are defined or not.

Returns

Object connected ot the current state of the iterator

Definition at line 666 of file THistManager.cxx.

THistManager::iterator & THistManager::iterator::operator++

(

)

Prefix increment operator. Incrementing / decrementing the current position of the iterator based on the direction.

Returns

State after incrementation

Definition at line 638 of file THistManager.cxx.

THistManager::iterator THistManager::iterator::operator++

(

int

)

Postfix increment operator. Incrementing / decrementing the current position of the iterator based on the direction, but returning the state before iteration

Returns

State before incrementation

Definition at line 646 of file THistManager.cxx.

THistManager::iterator & THistManager::iterator::operator--

(

)

Prefix decrement operator. Decrementing / incrementing the current position of the iterator based on the direction.

Returns

State after decrementation

Definition at line 652 of file THistManager.cxx.

THistManager::iterator THistManager::iterator::operator--

(

int

)

Postfix decrement operator. Decrementing / incrementing the current position of the iterator based on the direction, but returning the state before iteration

Returns

State before decrementation

Definition at line 660 of file THistManager.cxx.

THistManager::iterator & THistManager::iterator::operator=

(

const iterator &

rhs

)

Assignment operator. Initializing all values from the reference.

Parameters

[in]

ref

Returns

iterator after assignment.
