Version 1.0 1998 January 6

1.1 1998 January 7 -officially implements DataInput

1.2 1998 January 9 - add LERandomAccessFile

1.3 1998 August 28 1.4 1998 November 10 - add new address and phone.

1.5 1999 October 8 - use com.mindprod.ledatastream package name. Very similar to DataOutputStream except it writes little-endian instead of big-endian binary data. We can't extend DataOutputStream directly since it has only final methods. This forces us implement LEDataOutputStream with a DataOutputStream object, and use wrapper methods.

Field Detail

dis

protected final DataOutputStream dis

to get at big-Endian write methods of DataOutPutStream.

work

protected final byte[] work

work array for composing output.

Constructor Detail

LEDataOutputStream

public LEDataOutputStream(OutputStream out)

constructor.

Parameters:

out - the outputstream we write little endian binary data onto.

LEDataOutputStream

public LEDataOutputStream(String filename)
                   throws FileNotFoundException

Throws:

FileNotFoundException

Method Detail

close

public final void close()
                 throws IOException

Close stream.

Throws:

IOException - if close fails.

flush

public void flush()
           throws IOException

Flush stream without closing.

Throws:

IOException - if flush fails.

size

public final int size()

Get size of stream.

Returns:

bytes written so far in the stream. Note this is a int, not a long as you would exect. This because the underlying DataInputStream has a design flaw.

write
