withinBounds
public boolean withinBounds()
- Specified by:

in classOffset
-
setCurrentOffset
public void setCurrentOffset(int currentOffset)
- Specified by:
setCurrentOffset
in classSimpleSettableOffset
-
reset
public void reset()
Description copied from class:Offset
Resets the Offset to the position it was created or cloned with.
-
getBaseReadableOffset
public ReadableOffset getBaseReadableOffset()
Description copied from class:Offset
Returns 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 asFilteredOffset
and reduce reference indirection, when onlyReadableOffset
API is needed.- Specified by:
getBaseReadableOffset
in classOffset
-
getOffset
public int getOffset()
-
inspectRuntimeShape
public void inspectRuntimeShape(RuntimeShapeInspector inspector)
Description copied from interface:HotLoopCallee
Implementations 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 withCalledFromHotLoop
2. 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 typeSet
could beHashSet
orTreeSet
in 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.
