extends Object
implements Serializer

Specialized version of FixedIndexedWriter for writing ints, with no support for null values, and no verification that data is actually sorted, it just trusts you and takes your word for it

Method Details

open

public void open()
          throws IOException

Throws:

IOException

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

write

public void write(int objectToWrite)
           throws IOException

Throws:

IOException

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

getIterator

public it.unimi.dsi.fastutil.ints.IntIterator getIterator()
