\ j8@dZGddeZGddZdS)aKMemory allocation algorithm for vertex arrays and buffers. The region allocator is used to allocate vertex indices within a vertex domain's multiple buffers. ("Buffer" refers to any abstract buffer presented by :py:mod:`pyglet.graphics.vertexbuffer`. The allocator will at times request more space from the buffers. The current policy is to double the buffer size when there is not enough room to fulfil an allocation. The buffer is never resized smaller. The allocator maintains references to free space only; it is the caller's responsibility to maintain the allocated regions. ceZdZdZdZdS)AllocatorMemoryExceptiona"The buffer is not large enough to fulfil an allocation. Raised by `Allocator` methods when the operation failed due to lack of buffer space. The buffer should be increased to at least requested_capacity and then the operation retried (guaranteed to pass second time). c||_dS)N)requested_capacity)selfrs T/DATA/AppData/hermes/venv/lib/python3.11/site-packages/pyglet/graphics/allocation.py__init__z!AllocatorMemoryException.__init__Ss"4N)__name__ __module__ __qualname____doc__rr rrrJs-55555r rc^eZdZdZdZdZdZdZdZdZ dZ d Z d Z d Z d Zd ZdZdS) Allocatorz'Buffer space allocation implementation.capacitystartssizesc0||_g|_g|_dS)zCreate an allocator for a buffer of the specified capacity. :Parameters: `capacity` : int Maximum size of the buffer.
