Ids::IdAllocator< TYPES > Class Template Reference

#include <idallocator.h>

Detailed Description

template<class ... TYPES>
class Ids::IdAllocator< TYPES >

An ID allocator associates an id with a slice in an N number of arrays.

There are two versions of this type, an unsafe and a safe one. Both are implemented in the same way, providing a variadic list of types which is to be contained in the allocator and fetching each value by providing the index into the list of types, which means the members are nameless.

The thread safe allocator requires the Get-methods to be within an Enter/Leave lockstep phase.

Constructor & Destructor Documentation

IdAllocator()

template<class ... TYPES>

Ids::IdAllocator< TYPES >::IdAllocator ( Ids::Id32 maxid = 0xFFFFFFFF )

inline

constructor

Member Function Documentation

Alloc()

template<class ... TYPES>

Ids::Id32 Ids::IdAllocator< TYPES >::Alloc ( )

inline

Allocate an object.

Note

This purposefully hides the default allocation method and should definetly not be virtual!

Dealloc()

template<class ... TYPES>

void Ids::IdAllocator< TYPES >::Dealloc ( Ids::Id32 index )

inline

Deallocate an object. Just places it in freeids array for recycling.

FreeIds()

template<class ... TYPES>

Util::Array< Ids::Id32 > & Ids::IdAllocator< TYPES >::FreeIds ( )

inline

Returns the list of free ids.

Size()

template<class ... TYPES>

const Ids::Id32 Ids::IdAllocator< TYPES >::Size ( ) const

inline

return number of allocated ids
