Field Detail
- deoptimizationStartOffsets
```
protected int[] deoptimizationStartOffsets
```
- deoptimizationEncodings
```
protected byte[] deoptimizationEncodings
```
- deoptimizationObjectConstants
```
protected Object[] deoptimizationObjectConstants
```
- name
```
protected String name
```
  The name of the InstalledCode. Stored in a separate field so that it is available even after the code is no longer available. Note that the String is not pinned, so this field must not be accessed during garbage collection.
- tier
```
protected int tier
```
  The index of the compilation tier that was used to compile the respective code.
- installedCode
```
protected WeakReference<SubstrateInstalledCode> installedCode
```
  The handle to the compiled code for the outside world. We only have a weak reference to it, to avoid keeping code alive. Note that the both the InstalledCode and the weak reference are not pinned, so this field must not be accessed during garbage collection.
- constantsWalker
```
protected ObjectReferenceWalker constantsWalker
```
  Provides the GC with the root pointers embedded into the runtime compiled code. This object is accessed during garbage collection, so it must be pinned.
- allocator
```
protected PinnedAllocator allocator
```
  The pinned allocator used to allocate all code meta data that is accessed during garbage collection. It is released only after the code has been invalidated and it is guaranteed that no more stack frame of the code is present.
- codeObserverHandles
```
protected InstalledCodeObserver.InstalledCodeObserverHandle[] codeObserverHandles
```
