Detailed Description

template<typename Ty, class Hash, class Equal>
class utilmm::smart::ref_count::uniq_memory< Ty, Hash, Equal >

Unique instance memory manager.

Parameters

Ty	The type of managed cells
Hash	A hash functor for Ty
Equal	An equality functor for Ty

This class is a memory manager for the utilmm::smart::ref_count::manager class. It implements a memory where there's one and only one element with a given value.

In this memory we have the guarantee that there's no mem_cell pair with pointed values that return true when passed as argument to Equal

Member Function Documentation

template<typename Ty , class Hash , class Equal >

mem_cell utilmm::smart::ref_count::uniq_memory< Ty, Hash, Equal >::create

(

base_type *

ptr

)

Attachment of a new pointer.

This function adds a new pointer to the memory management.

Parameters

ptr	The pointer to manage

Returns

The cell associated to ptr

Note

if memory has allready a mem_cell equivalent to ptr then ptr is deleted

template<typename Ty , class Hash , class Equal >

void utilmm::smart::ref_count::uniq_memory< Ty, Hash, Equal >::destroy

(

mem_cell

c

)

Destroy a memory cell.

This function Will detroy a memory cell and the real pointed value

Parameters

c	The cell to destroy

template<typename Ty , class Hash , class Equal >

mem_cell utilmm::smart::ref_count::uniq_memory< Ty, Hash, Equal >::null_cell ( )

inline

null cell creation

This function create the cell corresponding to null

Returns

the null cell
