Detailed Description

A default allocator implementation based on global new and delete.

This implementation realizes the singleton pattern. An instance of the default allocator can be obtained through the static inline method mi::base::Default_allocator::get_instance().

Include File:

#include <mi/base/default_allocator.h>

Member Function Documentation

virtual void mi::base::Default_allocator::free ( void *  memory)

inlinevirtual

Releases the given memory block.

Implements mi::base::IAllocator::free through a global operator delete call.

Parameters

memory

A memory block previously allocated by a call to malloc(). If memory is NULL, no operation is performed.

Implements mi::base::IAllocator.

static IAllocator* mi::base::Default_allocator::get_instance ( )

inlinestatic

Returns the single instance of the default allocator.

virtual void* mi::base::Default_allocator::malloc ( Size  size)

inlinevirtual

Allocates a memory block of the given size.

Implements mi::base::IAllocator::malloc through a global non-throwing operator new call.

Parameters

size	The requested size of memory in bytes. It may be zero.

Returns

The allocated memory block.

Implements mi::base::IAllocator.
