   public ByteArray(int len) 

   public ByteArray(byte[] buf) 

   public ByteArray(byte[] buf, 
                    int offset) 

   public ByteArray(byte[] buf, 
                    int offset, 
                    int len)  throws IndexOutOfBoundsException

   public ByteArray(ByteArray parent, 
                    int offset, 
                    int len)  throws IndexOutOfBoundsException

   public final int length() 

   public final byte getByte(int index)  throws IndexOutOfBoundsException

   public final void setByte(int index, 
                             byte val)  throws IndexOutOfBoundsException

   public final void getBytes(int srcBegin, 
                              byte[] dst, 
                              int dstBegin, 
                              int length) 

   public final void setBytes(int dstBegin, 
                              byte[] src, 
                              int srcBegin, 
                              int length) 

   public final void setBytes(int dstBegin, 
                              ByteArray src, 
                              int srcBegin, 
                              int length) 

   public final byte[] toBytes() 

Returns a byte array exactly the right size for the valid data in the buf. Note that if this.buf is the right side it is returned directly, otherwise a new array is created of the right size. (Weird.)

Returns:

array of bytes

   public String toString() 

Overrides:

toString in class Object
