Puma::ConstSizeMemPool< N > Class Template Reference

#include <Puma/ConstSizeMemPool.h>

Description

template<int N>
class Puma::ConstSizeMemPool< N >

Constant size memory block pool.

Memory blocks are not freed before the pool is destroyed. Free blocks are inserted into a free list for reuse.

Following global functions are defined that use a constant size memory pool:

• Puma::malloc
• Puma::free
• Puma::clean

Template Parameters

N	Number of bytes for each memory block to allocate.

Public Member Functions
	ConstSizeMemPool ()
	Construct an empty memory pool.
	~ConstSizeMemPool ()
	Destroy the memory pool.
void *	alloc ()
	Get a block of memory.
void	free (void *block)
	Insert a block of memory into the free list for reuse.
void	clean ()
	Free all allocated memory blocks.

Static Public Member Functions
static ConstSizeMemPool &	inst ()
	Get the memory pool for this block size.

ConstSizeMemPool()

template<int N>

Puma::ConstSizeMemPool< N >::ConstSizeMemPool ( )

inline

Construct an empty memory pool.

~ConstSizeMemPool()

template<int N>

Puma::ConstSizeMemPool< N >::~ConstSizeMemPool ( )

inline

Frees all memory blocks allocated.

Member Function Documentation

alloc()

template<int N>

void * Puma::ConstSizeMemPool< N >::alloc ( )

inline

Get a block of memory.

If no free block is available, a new block of memory is allocated.

Returns

Pointer to the block of memory.

clean()

template<int N>

void Puma::ConstSizeMemPool< N >::clean ( )

inline

Free all allocated memory blocks.

free()

template<int N>

void Puma::ConstSizeMemPool< N >::free ( void * block )

inline

Insert a block of memory into the free list for reuse.

The memory block is freed when the pool is destroyed.

Parameters

block

Pointer to the memory block.

inst()

template<int N>

static ConstSizeMemPool & Puma::ConstSizeMemPool< N >::inst ( )

inlinestatic

Get the memory pool for this block size.

There is only one memory pool for each block size.

Returns

A reference to the memory pool.
