Methods of SimpleAllocator:

alloc
SimpleAllocatorBlock *SimpleAllocator::alloc(unsigned int size);

Description: Allocates a new block. Returns NULL if a block of the requested size cannot be allocated.
To free the allocated block, call block->free(), or simply delete the block pointer.

getContiguous
unsigned int SimpleAllocator::get_contiguous(void) const;

Description: Returns an upper-bound estimate of the size of the largest contiguous block that may be allocated. It is guaranteed that an attempt to allocate a block larger than this will fail, though it is not guaranteed that an attempt to allocate a block this size or smaller will succeed.

getFirstBlock
SimpleAllocatorBlock *SimpleAllocator::get_first_block(void) const;

Description: Returns a pointer to the first allocated block, or NULL if there are no allocated blocks.

getMaxSize
unsigned int SimpleAllocator::get_max_size(void) const;

Description: Returns the available space for allocated objects.

getTotalSize
unsigned int SimpleAllocator::get_total_size(void) const;

Description: Returns the total size of allocated objects.

isEmpty
bool SimpleAllocator::is_empty(void) const;

Description: Returns true if there are no blocks allocated on this page, or false if there is at least one.

output
void SimpleAllocator::output(ostream &out) const;

Description:

setMaxSize
void SimpleAllocator::set_max_size(unsigned int max_size);

Description: Changes the available space for allocated objects. This will not affect any already-allocated objects, but will have an effect on future calls to alloc().

write
void SimpleAllocator::write(ostream &out) const;

Description:
