Detailed Description

Un-typesafe base class for maintaining a free-list memory pool.

Definition at line 46 of file freelist.h.

GVX_DBG_REGISTER rutz::free_list_base::free_list_base ( std::size_t size_check )

Construct an (empty) free list.

All objects from this list must be of size size_check.

Definition at line 42 of file freelist.cc.

std::size_t rutz::free_list_base::alloc_size ( ) const [inline]

Query the chunk size that this freelist is for.

Definition at line 80 of file freelist.h.

void * rutz::free_list_base::allocate ( std::size_t bytes )

Allocate space for a new object.

If there are chunks available in the free list, one of those is returned; otherwise new memory is allocated with malloc() or equivalent.

Definition at line 48 of file freelist.cc.

void rutz::free_list_base::deallocate ( void * space )

Return an object to the free list.

Definition at line 61 of file freelist.cc.

std::size_t rutz::free_list_base::num_allocations ( ) const [inline]

Query how many allocations have been made.

Definition at line 83 of file freelist.h.

void rutz::free_list_base::release_free_nodes ( )

Release all nodes currently on the free list (e.g. to conserve memory).

Definition at line 68 of file freelist.cc.
