class ThreadSafeArena

Defined at line 41 of file ../../third_party/protobuf/src/google/protobuf/thread_safe_arena.h

This class provides the core Arena memory allocation library. Different

implementations only need to implement the public interface below.

Arena is not a template type as that would only be useful if all protos

in turn would be templates, which will/cannot happen. However separating

the memory allocation part from the cruft of the API users expect we can

use #ifdef the select the best implementation based on hardware / OS.

void ThreadSafeArena ()

void ThreadSafeArena (char * mem, size_t size)

void ThreadSafeArena (void * mem, size_t size, const AllocationPolicy & policy)

void ThreadSafeArena (const ThreadSafeArena & )

All protos have pointers back to the arena hence Arena must have

pointer stability.

void ~ThreadSafeArena ()

Destructor deletes all owned heap allocated objects, and destructs objects

that have non-trivial destructors, except for proto2 message objects whose

destructors can be skipped. Also, frees all blocks except the initial block

if it was passed in.

bool MaybeAllocateAligned (size_t n, void ** out)

This function allocates n bytes if the common happy case is true and

returns true. Otherwise does nothing and returns false. This strange

semantics is necessary to allow callers to program functions that only

have fallback function calls in tail position. This substantially improves

code for the happy path.
