Detailed Description

A Virtual Base Class for Dynamic Memory Managemen.

A Virtual Base Class for Dynamic Memory Management

This is a virtual base class for objects that manage their own dynamic memory allocation. Since it is a virtual base class, you have to derive something from it to use it.

Member Function Documentation

alloc()

virtual void* Arena::alloc ( size_t  a_sz )

pure virtual

Allocate a dynamic memory arena of size a_sz. A pointer to this memory should be returned.

Implemented in CArena, and BArena.

Referenced by ListBox< T >::define(), and BaseFab< Real >::define().

free()

virtual void Arena::free ( void *  a_pt )

pure virtual

A pure virtual function for deleting the arena pointed to by a_pt.

Implemented in CArena, and BArena.

Referenced by ListBox< T >::undefine(), and BaseFab< Real >::undefine().

align()

size_t Arena::align ( size_t  a_sz )

inlinestatic

Given a minimum required arena size of a_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.
