Public Member Functions

virtual void * alloc (size_t sz)

Allocates a dynamic memory arena of size sz.

virtual void free (void *pt)

Deletes the arena pointed to by pt.

Static Public Member Functions

static size_t align (size_t sz)

Given a minimum required arena size of sz bytes, this returns the next largest arena size that will hold an integral number of objects of the largest of the types void*, long, double and function pointer.

Detailed Description

: A Concrete Class for Dynamic Memory Management

This is the simplest dynamic memory management class derived from Arena.

Makes calls to operator new() and operator delete().

Member Function Documentation

void * BArena::alloc ( size_t sz ) [virtual]

Allocates a dynamic memory arena of size sz.

Returns a pointer to this memory.

Implements Arena.

void BArena::free ( void * pt ) [virtual]

Deletes the arena pointed to by pt.

Implements Arena.

size_t Arena::align ( size_t sz ) [static, inherited]

Given a minimum required arena size of sz bytes, this returns the next largest arena size that will hold an integral number of objects of the largest of the types void*, long, double and function pointer.
