ByteArrayIStream

• java.lang.Object
  • java.io.InputStream

Fields Summary
private final byte[]	m_buf
private final int	m_max
private int	m_pos
private static final int	NATIVE_COPY_THRESHOLD

Constructors Summary
public ByteArrayIStream(byte[] buf) this (buf, buf.length);
public ByteArrayIStream(byte[] buf, int length) if ($assert.ENABLED) $assert.ASSERT ((length >= 0) && (length <= buf.length), "invalid length: " + length); m_buf = buf; m_max = length;

Methods Summary
public final int	available() return m_max - m_pos;
public final void	close() Equivalent to {@link #reset()}. reset ();
public final int	read() if (m_pos >= m_max) return -1; else return 0xFF & m_buf [m_pos ++];
public final int	read(byte[] buf, int offset, int length) if ($assert.ENABLED) $assert.ASSERT ((offset >= 0) && (offset <= buf.length) && (length >= 0) && ((offset + length) <= buf.length), "invalid input (" + buf.length + ", " + offset + ", " + length + ")"); final int pos = m_pos; final int max = m_max; if (pos >= max) return -1; if (pos + length > max) length = max - pos; if (length <= 0) return 0; final byte [] mbuf = m_buf; if (length < NATIVE_COPY_THRESHOLD) for (int i = 0; i < length; ++ i) buf [offset + i] = mbuf [pos + i]; else System.arraycopy (mbuf, pos, buf, offset, length); m_pos += length; return length;
public final void	reset() Differs from the contruct for InputStream.reset() in that this method always resets the stream to the same it was immediately after creation. m_pos = 0;
public final long	skip(long n) if (m_pos + n > m_max) n = m_max - m_pos; if (n < 0) return 0; m_pos += n; return n;
