Inheritance diagram for libint2::MemoryManager:

Public Types
typedef intptr_t	Address
	Negative Address is used to denote an invalid address – hence signed integer.
typedef size_t	Size
typedef MemoryBlock< Address, Size >	MemBlock

Public Member Functions
virtual Address	alloc (const Size &size)=0
	Reserve a block and return its address.
virtual void	free (const Address &address)
	Release a block previously reserved using alloc.
Size	max_memory_used () const
	Returns the max amount of memory used up to this moment.
void	reset ()
	resets the state of MemoryManager; does not invalidate stats, however

Static Public Attributes
static const Address	InvalidAddress = -1

Protected Types
typedef std::list< std::shared_ptr< MemBlock > >	memblkset

Protected Member Functions
	MemoryManager (const Size &maxmem)
Size	maxmem () const
	Returns maxmem.
memblkset &	blocks ()
	Returns blocks.
std::shared_ptr< MemBlock >	superblock () const
	Returns the superblock.
std::shared_ptr< MemBlock >	steal_from_block (const std::shared_ptr< MemBlock > &blk, const Size &size)
	steals size memory from block blk and returns the new block
std::shared_ptr< MemBlock >	find_block (const Address &a)
	finds the block at Address a

Detailed Description

Class MemoryManager handles allocation and deallocation of raw memory (stack) provided at runtime of the library.
