Method Details

read

int read()
  throws IOException

Throws:

IOException

mark

void mark(int readLimit)
   throws IOException

Throws:

IOException

reset

void reset()
    throws IOException

Throws:

IOException

readUnsignedInt

long readUnsignedInt()
              throws IOException

Reads 4 input bytes and returns a long value in the range 0-2^32.

Returns:

long value

Throws:

IOException

readUnsignedLong

long readUnsignedLong()
               throws IOException

Reads 8 input bytes and returns a long value in the range 0-2^63. Values greater than 2^63 won't be read correctly since they are not supported by java.

Returns:

long value

Throws:

IOException

readASCII

String readASCII()
          throws IOException

Reads a 0 terminated ASCII string from input stream

Returns:

string value

Throws:

IOException
