LinkedListNode
An implementation of a very simple block allocator. This class can allocate ranges of nonnegative integers within a specified upper limit; it uses a simple first-fit algorithm to find the next available space.
Inheritance diagram
-
__init__
(from: SimpleAllocator)¶ Move constructor.
-
alloc
(size: int, alignment: int) → SimpleAllocatorBlock¶ 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
() → int¶ 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¶ Returns a pointer to the first allocated block, or NULL if there are no allocated blocks.
-
isEmpty
() → bool¶ Returns true if there are no blocks allocated on this page, or false if there is at least one.
