compareTo

public int compareTo(VSizeColumnarInts o)

Specified by:

compareTo in interface Comparable<VSizeColumnarInts>

getNumBytes

public int getNumBytes()

getSerializedSize

public long getSerializedSize()

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, org.apache.druid.segment.file.SegmentFileBuilder) call.

Specified by:

getSerializedSize in interface Serializer

writeTo

public void writeTo(WritableByteChannel channel,
 SegmentFileBuilder fileBuilder)
             throws IOException

Description copied from interface: Serializer

Writes the serialized form of this object. The entire object may be written to the provided channel, or the object may be split over the provided channel and files added to the {@link SegmentFileBuilder], where additional channels can be created via SegmentFileBuilder.addWithChannel(String, long). The latter approach is useful when the serialized form of the object is too large for a single smoosh container. At the time this javadoc was written, the max smoosh container size is limit to the max ByteBuffer size.

Specified by:

writeTo in interface Serializer

Throws:

IOException

get

public ColumnarInts get()

Specified by:

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

Specified by:

get in interface Supplier<ColumnarInts>

readFromByteBuffer

public static VSizeColumnarInts readFromByteBuffer(ByteBuffer buffer)

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

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
