Method Detail

fromIterable

public static VSizeColumnarMultiInts fromIterable(Iterable<VSizeColumnarInts> objectsIterable)

getClazz

public Class<? extends VSizeColumnarInts> getClazz()

Specified by:

getClazz in interface Indexed<IndexedInts>

size

public int size()

Specified by:

size in interface Indexed<IndexedInts>

get

public VSizeColumnarInts get(int index)

Specified by:

get in interface ColumnarMultiInts

Specified by:

get in interface Indexed<IndexedInts>

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. Subclasses may tighten this contract (GenericIndexed does this).

Specified by:

indexOf in interface Indexed<IndexedInts>

Parameters:

value - value to search for

Returns:

index of value, or a negative number

getSerializedSize

public long getSerializedSize()
                       throws IOException

Description copied from interface: Serializer

Returns the number of bytes, that this Serializer will write to the output _channel_ (not smoosher) on a Serializer.writeTo(java.nio.channels.WritableByteChannel, io.druid.java.util.common.io.smoosh.FileSmoosher) call.

Specified by:

getSerializedSize in interface Serializer

Throws:

IOException

writeTo

public void writeTo(WritableByteChannel channel,
                    FileSmoosher smoosher)
             throws IOException

Description copied from interface: Serializer

Writes serialized form of this object to the given channel. If parallel data streams are needed, they could be created with the provided smoosher.

Specified by:

writeTo in interface Serializer

Throws:

IOException

get

public ColumnarMultiInts get()

Specified by:

get in interface com.google.common.base.Supplier<ColumnarMultiInts>

readFromByteBuffer

public static VSizeColumnarMultiInts readFromByteBuffer(ByteBuffer buffer)

iterator

public Iterator<IndexedInts> iterator()

Specified by:

iterator in interface Iterable<IndexedInts>

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException

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
