示例1:
TEST(ArenaTest, AllocateBytes) {
Arena arena;
char* ptr = NULL;
// allocate kMinBlockSize / 4 bytes
ptr = arena.AllocateBytes(kMinBlockSize / 4);
EXPECT_TRUE(ptr != NULL);
EXPECT_EQ(arena.current_block(), ptr);
EXPECT_EQ(kMinBlockSize, arena.total_reserved_bytes());
EXPECT_EQ(arena.current_block() + kMinBlockSize / 4, arena.remained_buffer());
EXPECT_EQ(kMinBlockSize - kMinBlockSize / 4, arena.remained_buffer_size());
// allocate kMinBlockSize / 2 bytes
ptr = arena.AllocateBytes(kMinBlockSize / 2);
EXPECT_TRUE(ptr != NULL);
EXPECT_EQ(arena.current_block() + kMinBlockSize / 4, ptr);
EXPECT_EQ(kMinBlockSize, arena.total_reserved_bytes());
EXPECT_EQ(arena.current_block() + kMinBlockSize * 3 / 4, arena.remained_buffer());
EXPECT_EQ(kMinBlockSize / 4, arena.remained_buffer_size());
// allocate kMinBlockSize bytes
ptr = arena.AllocateBytes(kMinBlockSize);
EXPECT_TRUE(ptr != NULL);
EXPECT_EQ(arena.current_block(), ptr);
EXPECT_EQ(kMinBlockSize * 3, arena.total_reserved_bytes());

// reset
arena.Reset();
