template<typename P, typename T, typename U = T>
class DLListImpl< P, T, U >

Template class used for implementing an list of object retreived from a pool

Definition at line 28 of file DLList.hpp.

Member Function Documentation

template<typename P , typename T, typename U >

void DLListImpl< P, T, U >::add ( Ptr< T > &  p )

inline

Add object to list

MUST be seized from correct pool

Definition at line 260 of file DLList.hpp.

Here is the caller graph for this function:

template<typename P , typename T, typename U >

void DLListImpl< P, T, U >::add ( Uint32  first, Ptr< T > &  last  )

inline

Add a list to list all elements must be correctly initilized correctly wrt next/prev

Definition at line 279 of file DLList.hpp.

Here is the call graph for this function:

template<typename P , typename T , typename U >

bool DLListImpl< P, T, U >::findId ( Uint32  i ) const

inline

Check if i is allocated.

Definition at line 252 of file DLList.hpp.

template<typename P , typename T, typename U >

bool DLListImpl< P, T, U >::first ( Ptr< T > &  p ) const

inline

Update ptr to first element in list

Returns

True if element exists, false otherwise

Update ptr to first element in list

Return i

Definition at line 406 of file DLList.hpp.

Here is the caller graph for this function:

template<typename P , typename T, typename U >

void DLListImpl< P, T, U >::getPtr ( Ptr< T > &  p, Uint32  i  ) const

inline
