Class ByteBuffer

public class ByteBuffer
extends java.lang.Object

A byte buffer is a flexible array which grows when elements are appended. There are also methods to append names to byte buffers and to convert byte buffers to names.

This is NOT part of any API supported by Sun Microsystems. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

Field Summary

byte[]	elems An array holding the bytes in this buffer; can be grown.
int	length The current number of defined bytes in this buffer.

Constructor Summary

ByteBuffer()
Create a new byte buffer.

ByteBuffer(int initialSize)
Create a new byte buffer with an initial elements array of given size.

Method Summary

void	appendByte(int b) Append byte to this buffer.
void	appendBytes(byte[] bs) Append all bytes from given byte array.
void	appendBytes(byte[] bs, int start, int len) Append `len' bytes from byte array, starting at given `start' offset.
void	appendChar(int x) Append a character as a two byte number.
void	appendDouble(double x) Append a double as a eight byte number.
void	appendFloat(float x) Append a float as a four byte number.
void	appendInt(int x) Append an integer as a four byte number.
void	appendLong(long x) Append a long as an eight byte number.
void	appendName(Name name) Append a name.
private void	copy(int size)
void	reset() Reset to zero length.
Name	toName(Names names) Convert contents to name.
