Detailed Description

template<class Var>
class Gecode::VarArray< Var >

Variable arrays

Variable arrays store variables. They are typically used for storing the variables being part of a solution.

Never use them for temporary purposes, use argument arrays instead.

Variable arrays can be enlarged dynamically. For memory efficiency, the initial array is allocated in the space. When adding variables, it is automatically resized and allocated on the heap.

Member Function Documentation

template<class Var>
const VarArray< Var > & Gecode::VarArray< Var >::operator= ( const VarArray< Var > &  a  )  [inline]

Initialize from variable array a (share elements).

Definition at line 604 of file array.hpp.

template<class Var >
int Gecode::VarArray< Var >::size ( void   )  const [inline]

Return size of array (number of elements).

Definition at line 611 of file array.hpp.

template<class Var >
void Gecode::VarArray< Var >::resize ( Space home,
int  m 
) [inline]

Insert or remove (uninitialized!) elements at the end such that size becomes m.

Definition at line 617 of file array.hpp.

template<class Var >
Var & Gecode::VarArray< Var >::operator[] ( int  i  )  [inline]

Return variable at position i.

Definition at line 647 of file array.hpp.

template<class Var >
const Var & Gecode::VarArray< Var >::operator[] ( int  i  )  const [inline]

Return variable at position i.

Definition at line 654 of file array.hpp.

template<class Var>
void Gecode::VarArray< Var >::add ( Space home,
const Var &  v 
) [inline]

Insert a new element v at the end of the array (increase size by 1).

Definition at line 661 of file array.hpp.

template<class Var>
void Gecode::VarArray< Var >::update ( Space home,
bool  share,
VarArray< Var > &  a
