Detailed Description

template<class T, unsigned nlnk>
class concepts::Joiner< T, nlnk >

Joiner class with multiple successors, i.e. it can represent a b-ary tree with b=nlnk. A Joiner is a node in this tree. with b=1 the tree degraded to a forward linked list.

Adding a new node at the beginning of the list is as easy as

Joiner<int, 1>* list;
int a = 2;
list = new Joiner<int, 1>(a, list);

It is not possible to use unique_ptr and Joiner together in a construction like

unique_ptr<Joiner<int, 1> > list;

though. The assignment operator = of unique_ptr releases (ie. deletes) the old object when a new object is assigned. In the statement above, the list on the right hand side would be deleted...

Note

this class would more probably be called BAryTreeNode

Parameters

T	Class to be stored
nlnk	Number of successors (ie. links)

Constructor & Destructor Documentation

Joiner()

template<class T , unsigned nlnk>

concepts::Joiner< T, nlnk >::Joiner ( const T &  val, Joiner< T, nlnk > *  lnk = 0  )

inline

Constructor. Fills the container and sets the successors to default of NULL. If a successor is given as argument its filled in as the last successor.

Parameters

val	Content of the container.
lnk	Initialization value for the last successor.

Definition at line 125 of file scannerConnectors.hh.

~Joiner()

template<class T , unsigned nlnk>

concepts::Joiner< T, nlnk >::~Joiner ( )

inline

Empty destructor. To delete the list/tree do it by hand or use destructor (only if T pointer).

Definition at line 88 of file scannerConnectors.hh.

Member Function Documentation

destructor()

template<class T , unsigned nlnk>

void concepts::Joiner< T, nlnk >::destructor ( Joiner< T, nlnk > *&  j, bool  values = true  )

static

Static function to delete the list/tree. This Function is only valid if T is a pointer type allocated with new().

Parameters

j	Root of the list/tree. It is overwritten with 0

Definition at line 135 of file scannerConnectors.hh.

operator[]()

template<class T , unsigned nlnk>

Joiner *& concepts::Joiner< T, nlnk >::operator[] ( uint  i )

inline

Index operator for the container.

Precondition

i < nlnk

Returns

The ith successor.

Definition at line 101 of file scannerConnectors.hh.

value()

template<class T , unsigned nlnk>

T & concepts::Joiner< T, nlnk >::value ( )

inline

Returns the content of the container.

Definition at line 107 of file scannerConnectors.hh.
