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 Detail

getDataInput

DataInputBuffer getDataInput()

Return an input stream that will read from the slice.

getInputBitStream

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
