  - TPSBuffer
```
public TPSBuffer(int len,
                 byte b)
```
    Creates a Buffer of length 'len', with each byte initialized to 'b'.
  - TPSBuffer
```
public TPSBuffer(byte b)
```
    Creates a buffer from only one byte
    
    Parameters:
    
    b -

```
public TPSBuffer(int len)
```
    Creates a Buffer of length 'len', initialized to zeroes.
  - TPSBuffer
```
public TPSBuffer(byte[] inBuf)
```
    Creates a Buffer of length 'len', initialized from 'buf'. 'buf' must contain at least 'len' bytes.

  - at
```
public byte at(int i)
```
  - setAt
```
public void setAt(int i,
                  byte value)
```
  - equals
```
public boolean equals(TPSBuffer cmp)
```
    Returns true if the two buffers are the same length and contain the same byte at each offset.

public void add(TPSBuffer addend)

public void set(TPSBuffer newContents)
```
  - set
```
public void set(byte[] newContents)
```
  - add
```
public void add(byte b)
```
    Append operators.
  - prependBytes
```
public void prependBytes(byte[] preBytes)
```
  - addBytes
```
public void addBytes(byte[] addBytes)
```
  - toBytesArray
```
public byte[] toBytesArray()
```
  - size
```
public int size()
```
    The length of buffer. The actual amount of space allocated may be higher--see capacity().
  - zeroize
```
public void zeroize()
```
    Sets all bytes in the buffer to 0.
  - resize
```
public void resize(int newLen)
```
    Changes the length of the Buffer. If 'newLen' is shorter than the current length, the Buffer is truncated. If 'newLen' is longer, the new bytes are initialized to 0. If 'newLen' is the same as size(), this is a no-op.
  - substr
```
public TPSBuffer substr(int start,
                        int theLen)
```
    Returns a new Buffer that is a substring of this Buffer, starting from offset 'start' and continuing for 'len' bytes. This Buffer must have size() >= (start + len).
  - substr
```
public TPSBuffer substr(int start)
```
    Get the SubString from start to the end
    
    Parameters:
    
    start -
    
    Returns:
