Class LEDataOutputStream

java.lang.Object
  gov.nist.microanalysis.EPQTools.LEDataOutputStream

All Implemented Interfaces:

java.io.DataOutput

public class LEDataOutputStream
extends java.lang.Object
implements java.io.DataOutput

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

d

protected java.io.DataOutputStream d

to get at big-Endian write methods of DataOutPutStream

Constructor Detail

LEDataOutputStream

public LEDataOutputStream(java.io.OutputStream out)

constructor

Parameters:

out - the outputstream we ware to write little endian binary data onto

Method Detail

close

public final void close()
                 throws java.io.IOException

Throws:

java.io.IOException

flush

public void flush()
           throws java.io.IOException

Throws:

java.io.IOException

size

public final int size()

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

public final void write(byte[] b)
                 throws java.io.IOException

Specified by:

write in interface java.io.DataOutput

                        int off,
                        int len)
                 throws java.io.IOException

Specified by:

write in interface java.io.DataOutput

Throws:

java.io.IOException

Specified by:

write in interface java.io.DataOutput

Throws:

java.io.IOException

writeByte

public final void writeByte(int v)
                     throws java.io.IOException

Specified by:

writeChar in interface java.io.DataOutput

Parameters:

v -

Throws:

java.io.IOException

writeChars

public final void writeChars(java.lang.String s)

Throws:

java.io.IOException

writeFloat

public final void writeFloat(float v)
                      throws java.io.IOException

like DataOutputStream.writeFloat.

Specified by:
