getBaseReadableOffset
Description copied from class:OffsetReturns the same offset ("this") or a readable "view" of this offset, which always returns the same value fromReadableOffset.getOffset(), as this offset. This method is useful for "unwrapping" such offsets asFilteredOffsetand reduce reference indirection, when onlyReadableOffsetAPI is needed.- Specified by:

inspectRuntimeShape
Description copied from interface:HotLoopCalleeImplementations of this method should callinspector.visit()with all fields of this class, which meet two conditions: 1. They are used in methods of this class, annotated withCalledFromHotLoop2. They are either: a. Nullable objects b. Instances of HotLoopCallee c. Objects, which don't always have a specific class in runtime. For example, a field of typeSetcould beHashSetorTreeSetin runtime, depending on how this instance (the instance on which inspectRuntimeShape() is called) is configured. d. ByteBuffer or similar objects, where byte order matters e. boolean flags, affecting branch taking f. Arrays of objects, meeting any of conditions a-e.
