nl_tokens: Encode a simple integer . Integers are encoded as a simple base - 256 byte sequence most significant byte first prefixed with a length byte . In principle we support arbitrary integer sizes in practice Javascript doesn t even ** have ** integers so some precision might get lost .
pl_tokens: function encodeIntegerish ( val , type ) { var i , arr , buf ; // Get the bytes that we're going to encode. arr = intArray ( val ) ; // Now that we know the length, we allocate a buffer of the required size. // We set the type and length bytes appropriately. buf = new Buffer ( 2 + arr . length ) ; buf [ 0 ] = <mask> ; buf [ 1 ] = arr . length ; // Copy the bytes into the array. for ( i = 0 ; i < arr . length ; i ++ ) { buf [ i + 2 ] = arr [ i ] ; } return buf ; }
