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.

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]contContainer to be iterated over (not modified)
[in]startposStart position for the iteration
[in]forwardIf true iterator is a forward iterator

Definition at line 651 of file AliParticleContainer.cxx.

AliParticleContainer::all_iterator::all_iterator ( const all_iterator other)

Copy constructor. For the underlying container the pointer is copied.

Parameters
[in]otherReference for the copy

Definition at line 666 of file AliParticleContainer.cxx.

Member Function Documentation

bool AliParticleContainer::all_iterator::operator!= ( const all_iterator other) const

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

Parameters
[in]otherObject to compare to.
Returns
If true the positions of the two iterators match

Definition at line 694 of file AliParticleContainer.cxx.

AliVParticle * AliParticleContainer::all_iterator::operator* ( ) const

Dereferencing operator. Accessing cluster at the current position of the iterator in the cluster container

Returns

Definition at line 755 of file AliParticleContainer.cxx.

AliParticleContainer::all_iterator & AliParticleContainer::all_iterator::operator++ ( )

Incrementation prefix operator. Incrementing/Decrementing the postion of the iterator in the array based on the direction.

Returns
State of the iterator (reference) after iteration.

Definition at line 703 of file AliParticleContainer.cxx.

AliParticleContainer::all_iterator AliParticleContainer::all_iterator::operator++ ( int  )

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

Parameters
[in]Notused, only defining the operator as postfix operator
Returns
State of the iterator (copy) before iteration

Definition at line 718 of file AliParticleContainer.cxx.

AliParticleContainer::all_iterator & AliParticleContainer::all_iterator::operator-- ( )

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

Returns
State of the iterator (reference) after iteration.

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]Notused, only defining the operator as postfix operator
Returns
State of the iterator (copy) before iteration

Definition at line 744 of file AliParticleContainer.cxx.

AliParticleContainer::all_iterator & AliParticleContainer::all_iterator::operator= ( const all_iterator other)

Assignmet operator, copying properties of the reference iterator

Parameters
[in]otherReference for the assignment
Returns
This object after the assingment
