Detailed Description

A Concrete Class for Dynamic Memory Management.

This is a coalescing memory manager. It allocates (possibly) large chunks of heap space and apportions it out as requested. It merges together neighboring chunks on each free().

Constructor & Destructor Documentation

CArena::CArena ( size_t  a_hunk_size = 0)

: Construct a coalescing memory manager. `a_hunk_size' is the minimum size of hunks of memory to allocate from the heap. If a_hunk_size == 0 we use DefaultHunkSize as specified below.

virtual CArena::~CArena ( )
virtual

The destructor.

CArena::CArena ( const CArena a_rhs)
private

Member Function Documentation

virtual void* CArena::alloc ( size_t  a_nbytes)
virtual

Allocate some memory.

Implements Arena.

virtual void CArena::free ( void *  a_vp)
virtual

Free up allocated memory. Merge neighboring free memory chunks into largest possible chunk.

Implements Arena.

CArena& CArena::operator= ( const CArena a_rhs)
private
