Method Detail

get

byte get(int i)

Return the byte value at the specified index.

Parameters:

i - The index.

Returns:

The byte.

readInt

int readInt(int pos)

Reads a coded length.

Parameters:

pos - The starting position.

Returns:

The length coded at pos.

arraycopy

void arraycopy(int pos,
             byte[] dest,
             int destPos,
             int len)

Copy data from the backing buffer into the caller's array.

Parameters:

pos - The starting position in the backing buffer.

dest - The caller's array.

destPos - The starting position in the caller's array.

len - The #of bytes to copy.

size

int size()

IOException

writeOn

int writeOn(OutputStream out,
          int off,
          int len)
            throws IOException

Write len bytes starting at off onto the caller's stream.

Parameters:

out - The output stream.

off - The index of the first byte to be written.

len - The #of bytes to be written.

Returns:

The #of bytes written.

Throws:

IOException

clone
