class BlockAllocator

Defined at line 19 of file ../../src/ui/lib/escher/util/block_allocator.h

A BlockAllocator allocates raw CPU data from fixed-size blocks. To minimize

overhead, allocations are not freed individually; the Reset() method frees

all allocations at once. Large allocations may exceed the size of a block;

these are allocated separately (although still freed at the same time).

void Reset ()

Invalidates all previously-allocated pointers. Large blocks are freed, and

fixed-size blocks are made available for reuse.
