Method Detail

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException

size

public int size()

Description copied from interface: Indexed

Number of elements in the value set

Specified by:

size in interface Indexed<IndexedInts>

get

public IndexedInts get(int index)

Description copied from interface: ColumnarMultiInts

Returns the values at a given row index. The IndexedInts object may potentially be reused, so callers should not keep references to it.

Specified by:

get in interface ColumnarMultiInts

Specified by:

get in interface Indexed<IndexedInts>

getUnshared

public IndexedInts getUnshared(int index)

Description copied from interface: ColumnarMultiInts

Returns the values at a given row index. The IndexedInts object will not be reused. This method may be less efficient than plain "get".

Specified by:

getUnshared in interface ColumnarMultiInts

indexOf

public int indexOf(IndexedInts 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 unless Indexed.isSorted() returns true, in which case it will be a negative number equal to (-(insertion point) - 1), in the manner of Arrays.binarySearch.

Specified by:

indexOf in interface Indexed<IndexedInts>

Parameters:

value - value to search for

Returns:

index of value, or a negative number (equal to (-(insertion point) - 1) if Indexed.isSorted())

iterator

public Iterator<IndexedInts> iterator()

Specified by:

iterator in interface Iterable<IndexedInts>

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
