Detailed Description

Implementation of Pool that satisfies requests using an Allocator.

Constructor & Destructor Documentation

pw::allocator::AllocatorAsPool::AllocatorAsPool	(	Allocator &	allocator,
		const Layout &	layout
	)

Construct a Pool from an Allocator.

Parameters

allocator	The allocator used to create fixed-size allocations.
layout	The size and alignment of the memory to be returned from this pool.

void * pw::allocator::AllocatorAsPool::DoAllocate ( )

overrideprivatevirtual

Returns a chunk of memory with this object's fixed layout.

Like pw::allocator::Allocate, returns null if memory is exhausted.

Return values

The	allocated memory.

void pw::allocator::AllocatorAsPool::DoDeallocate ( void * ptr )

overrideprivate

Releases a previously-allocated block of memory.

The given pointer must have been previously provided by this memory resource; otherwise the behavior is undefined.

Parameters

[in] ptr Pointer to previously-allocated memory.
