Method Detail

readUnsignedInt

public final long readUnsignedInt()
                           throws IOException

Read four input bytes and return a long value in the range 0 through 4294967295. Let a, b, c, d be the four bytes. The value returned is:

   ( b[ 0 ] & 0xFF ) << 24 ) | 
   ( ( b[ 1 ] & 0xFF ) << 16 ) | 
   ( ( b[ 2 ] & 0xFF ) << 8 ) | 
   ( b[ 3 ] & 0xFF )
 

Returns:

the unsigned 32-bit value.

Throws:

EOFException - if this stream reaches the end before reading all the bytes.

IOException - if an I/O error occurs.
