   +----wb.BytePackOutputStream
public class BytePackOutputStream
extends Object
This class lets you write primitive Java data types to a byte array in a portable way. Primitive data types are well understood types with associated operations. For example, an Integer is considered to be a good primitive data type. The data can be converted back using a ByteUnPackInputStream.

Variable Index

o buf
The buffer where data is stored.
o count
The number of bytes in the buffer.
o outstream
The real stream onto which the byte array will be written

Constructor Index

o BytePackOutputStream(OutputStream)
Creates a new BytePackOutputStream.

Method Index

o size()
Returns the current size of the local buffer which would be written when sync'd
o sync()
Writes a byte buffer to the stream that was specified during instantiation.
o sync(OutputStream)
Writes a byte buffer to the specified stream.
o writeBoolean(boolean)
Writes a boolean.
o writeByte(int)
Writes an 8 bit byte.
o writeBytes(String)
Writes a String as a sequence of bytes.
o writeChar(int)
Writes a 16 bit char.
o writeChars(String)
Writes a String as a sequence of chars.
o writeDouble(double)
Writes a 64 bit double.
o writeFloat(float)
Writes a 32 bit float.
o writeInt(int)
Writes a 32 bit int.
o writeLong(long)
Writes a 64 bit long.
o writeShort(int)
Writes a 16 bit short.

Variables

o buf 
  protected byte buf[]
The buffer where data is stored.
o count 
  protected int count
The number of bytes in the buffer.
o outstream 
  protected OutputStream outstream
The real stream onto which the byte array will be written

Constructors

o BytePackOutputStream 
  public BytePackOutputStream(OutputStream out)
Creates a new BytePackOutputStream.
Parameters:
out - the output stream
