Constructors Summary
public ReaderUTF8(InputStream is) Constructor. param is A byte input stream. this.is = is;

Methods Summary
public void	close() Closes the stream. exception IOException If any IO errors occur. is.close();
public int	read(char[] cbuf, int off, int len) Reads characters into a portion of an array. param cbuf Destination buffer. param off Offset at which to start storing characters. param len Maximum number of characters to read. exception IOException If any IO errors occur. exception UnsupportedEncodingException If UCS-4 character occur in the stream. int num = 0; int val; while (num < len) { if ((val = is.read()) < 0) return (num != 0)? num: -1; switch (val & 0xf0) { case 0xc0: case 0xd0: cbuf[off++] = (char)(((val & 0x1f) << 6) | (is.read() & 0x3f)); break; case 0xe0: cbuf[off++] = (char)(((val & 0x0f) << 12) | ((is.read() & 0x3f) << 6) | (is.read() & 0x3f)); break; case 0xf0: // UCS-4 character throw new UnsupportedEncodingException(); default: cbuf[off++] = (char)val; break; } num++; } return num;
public int	read() Reads a single character. return The character read, as an integer in the range 0 to 65535 (0x00-0xffff), or -1 if the end of the stream has been reached. exception IOException If any IO errors occur. exception UnsupportedEncodingException If UCS-4 character occur in the stream. int val; if ((val = is.read()) < 0) return -1; switch (val & 0xf0) { case 0xc0: case 0xd0: val = ((val & 0x1f) << 6) | (is.read() & 0x3f); break; case 0xe0: val = ((val & 0x0f) << 12) | ((is.read() & 0x3f) << 6) | (is.read() & 0x3f); break; case 0xf0: // UCS-4 character throw new UnsupportedEncodingException(); default: break; } return val;
