Here is the call graph for this function:

template<typename P , typename T, typename U >

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

inline

Update ptr to first element in list

Return i

Here is the caller graph for this function:

template<typename P , typename T, typename U >

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

inline

Update i & p value according to i

Definition at line 320 of file SLList.hpp.

template<typename P , typename T, typename U >
