Bi-directional iterator over all particles in the array. The iterator is used in the standard way a c++ iterator is used. The container is responsible creating it. Afterwards one uses the prefix or postfix increment or decrement operator, depending on the direction of the iteration.

AliParticleContainer cont;
for(AliParticleContainer::iterator it = cont.begin(); it != cont.end(); ++cont){
  std::cout << "Particle pt: " << (*it)->Pt() std::endl;      // do something with the particle inside
}

If you are using c++11 this reduces to

for(auto it : cont){
  std::cout << "Particle pt: " << it->Pt() std::endl;      // do something with the particle inside
}

using c++11 range-based iterations.

As the postfix operator needs to perform a copy of the iterator, the prefix operator will have a better performance and should be preferred.

Constructor & Destructor Documentation

AliParticleContainer::all_iterator::all_iterator	(	const AliParticleContainer *	cont,
		int	startpos,
		bool	forward = true
	)

Content of all_iterator Constructor, inializing the iterator with

• Particle container to iterate over
• Starting position for the iteration
• Direction of the iteration (default: forward)

Note: Iterators should be created by the object it iterates over and not by hand.

Parameters

[in]	cont	Container to be iterated over (not modified)
[in]	startpos	Start position for the iteration
[in]	forward	If true iterator is a forward iterator

Returns

State of the iterator (copy) before iteration

Definition at line 718 of file AliParticleContainer.cxx.

AliParticleContainer::all_iterator & AliParticleContainer::all_iterator::operator--

(

Definition at line 729 of file AliParticleContainer.cxx.

AliParticleContainer::all_iterator AliParticleContainer::all_iterator::operator--

(

int

)

Decrementation postfix operator. Decrementing/Incrementing the postion of the iterator in the array based on the direction.

Parameters

[in]
