Method Detail

ensureSize

public void ensureSize(int size)

setSize

public void setSize(int size)

setValues

public void setValues(int[] values,
                      int size)

Sets the values from the given array. The given values array is not reused and not prone to be mutated later. Instead, the values from this array are copied into an array which is internal to ArrayBasedIndexedInts.

setValue

public void setValue(int index,
                     int value)

size

public int size()

Specified by:

size in interface IndexedInts

get

public int get(int index)

inspectRuntimeShape

public void inspectRuntimeShape(RuntimeShapeInspector inspector)

Description copied from interface: HotLoopCallee

Implementations of this method should call inspector.visit() with all fields of this class, which meet two conditions: 1. They are used in methods of this class, annotated with CalledFromHotLoop 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 type Set could be HashSet or TreeSet 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.
