                    Class<? extends T> clazz)

Method Detail

getClazz

public Class<? extends T> getClazz()

Specified by:

getClazz in interface Indexed<T>

size

public int size()

Specified by:

size in interface Indexed<T>

get

public T get(int index)

Specified by:

get in interface Indexed<T>

indexOf

public int indexOf(T value)

Description copied from interface: Indexed

Returns the index of "value" in this Indexed object, or a negative number if the value is not present. The negative number is not guaranteed to be any particular number. Subclasses may tighten this contract (GenericIndexed does this).

Specified by:

indexOf in interface Indexed<T>

Parameters:

value - value to search for

Returns:

index of value, or a negative number

iterator

public Iterator<T> iterator()

Specified by:

iterator in interface Iterable<T>

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.

Specified by:

inspectRuntimeShape in interface HotLoopCallee
