com.bigdata.io
Interface IFixedDataRecord

All Superinterfaces:

IByteArraySlice, IDataRecord

All Known Implementing Classes:

AbstractFixedByteArrayBuffer, FixedByteArrayBuffer

public interface IFixedDataRecord
extends IDataRecord

Interface adds some methods for stream-based access to IDataRecord.

Note: These methods are isolated on this interface to prevent confusion with the stream-based semantics of the ByteArrayBuffer.

Method Summary

DataInputBuffer	getDataInput() Return an input stream that will read from the slice.
it.unimi.dsi.io.InputBitStream	getInputBitStream() Return a bit stream that will read from the slice.
void	writeOn(DataOutput out) Write the slice on the output stream.
void	writeOn(OutputStream os) Write the slice on the output stream.
void	writeOn(OutputStream os, int aoff, int alen) Write part of the slice on the output stream.

Method Detail

getDataInput

DataInputBuffer getDataInput()

Return an input stream that will read from the slice.

getInputBitStream

it.unimi.dsi.io.InputBitStream getInputBitStream()

Return a bit stream that will read from the slice.

Note: You DO NOT need to close this stream since it is backed by a byte[]. In fact, InputBitStream.close() when backed by a byte[] appears to have relatively high overhead, which is weird.

writeOn

void writeOn(OutputStream os)
             throws IOException

Write the slice on the output stream.

Parameters:

os - The output stream.

Throws:

IOException

writeOn

void writeOn(DataOutput out)
             throws IOException

Write the slice on the output stream.

Parameters:

os - The output stream.

Throws:

IOException

writeOn

void writeOn(OutputStream os,
             int aoff,
             int alen)
             throws IOException

Write part of the slice on the output stream.

Parameters:

os - The output stream.

Throws:

IOException
