class Apple
{
}
static void Main(string[] args)
{
Apple apple = ObjectAllocatorHolder<Apple>.Allocate();
ObjectAllocatorHolder<Apple>.Free(apple);
}Alternatively, you may want do some cleanup when Free
class ReusableApple : IReusableObject
{
public bool eaten;
public void ReInit() // will be called upon Free
{
eaten = false;
}
}
static void TestSimpleReusableObjectPool()
{
Apple apple = ObjectAllocatorHolder<Apple>.Allocate();
ObjectAllocatorHolder<Apple>.Free(apple);
}Extend BaseRefCounter and implement OnCleanUp
class AppleWithRefCounter : BaseRefCounter
{
public static AppleWithRefCounter Alloc()
{
AppleWithRefCounter apple = ObjectAllocatorHolder<AppleWithRefCounter>.Allocate();
return apple;
}
public bool eaten;
protected override void OnCleanUp()
{
eaten = false;
ObjectAllocatorHolder<AppleWithRefCounter>.Free(this);
}
}
static void TestReferenceCounteredObjectPool()
{
AppleWithRefCounter apple = AppleWithRefCounter.Alloc();
apple.ReleaseReference(); // compile will fail, if not release thanks to code analysis
}Alternatively, if you want to avoid class extension, implement IRefCounter and delegate to RefCounter instead.
class AppleWithRefCounter2 : IRefCounter
{
RefCounter _refCounter;
public static AppleWithRefCounter2 Alloc()
{
AppleWithRefCounter2 apple = ObjectAllocatorHolder<AppleWithRefCounter2>.Allocate();
return apple;
}
public int RefCount {
get
{
return _refCounter.RefCount;
}
}
protected void OnCleanUp()
{
eaten = false;
ObjectAllocatorHolder<AppleWithRefCounter2>.Free(this);
}
public void AcquireReference()
{
_refCounter.AcquireReference();
}
public void ReleaseReference()
{
_refCounter.ReleaseReference();
}
public void ReInit()
{
_refCounter.ReInit();
}
public bool eaten;
}
static void TestReferenceCounteredObjectPool2()
{
AppleWithRefCounter2 apple = AppleWithRefCounter2.Alloc();
apple.ReleaseReference(); // compile will fail, if not release thanks to code analysis
}
