Out IMP::core::gather ( h,
f,
Out  out 
)

Gather all the particles in the hierarchy that meet some criteria.

fboolean function / functor that returns true on desired particles
outa output iterator for appending the result
Returns
the output iterator

K0  k0,
V0  v0,

+ Here is the call graph for this function:

template<class H , class Out , class F >
Out IMP::core::gather_slice ( h,
f,
Out  out 
)

Gather all the uppermost particles in the hierarchy that meet some criteria.

Descent in the tree terminates when a node is gathered so that none of its children are explored.

+ Here is the call graph for this function:

template<class ND >
std::ostream& IMP::core::show ( Hierarchy  h,
std::ostream &  out = std::cout 
)

Print the hierarchy using a given decorator to display each node.

template<class HD , class F >
F IMP::core::visit_breadth_first ( HD  d,
f 
)

Apply the visitor to each particle, breadth first.

Parameters
[in]dThe Hierarchy for the tree in question
[in]fThe visitor to be applied. This is passed by reference. A branch of the traversal stops when f returns false.

template<class HD , class F >
F IMP::core::visit_breadth_first_with_data ( HD  d,
f,
typename F::result_type  i 
)

Apply functor F to each particle, traversing the hierarchy breadth first.

This method allows data to be associated with each visited node. The data of the parent is passed to each invocation of the child.

Parameters
[in]dThe Hierarchy for the tree in question
[in]fThe functor to be applied F must define a type Data which is returned by each call. The result of the parent call is passed as the second argument to the operator() of the child. e.g. struct DepthVisitor { typedef int result_type; result_type operator()(kernel::Particle *p, int i) const { if (p==nullptr) return 0; else return i+1; } };
[in]iThe data to be used for d (since it has no relevant parent)
Returns
A copy of the functor passed in. Use this if you care about the functor state.
