public class BDecoder extends Object
BEValue
s.
A bencoded byte stream can represent byte arrays, numbers, lists and
maps (dictionaries).
It currently contains a hack to indicate a name of a dictionary of
which a SHA-1 digest hash should be calculated (the hash over the
original bencoded bytes).Constructor and Description |

BDecoder(InputStream in)
Initalizes a new BDecoder.

Modifier and Type | Method and Description |
---|---|
BEValue |
bdecode()
Gets the next indicator and returns either null when the stream
has ended or bdecodes the rest of the stream and returns the
appropriate BEValue encoded object.
|
static BEValue |
bdecode(InputStream in)
Creates a new BDecoder and immediatly decodes the first value it
sees.
|
BEValue |
bdecodeBytes()
Returns the next bencoded value on the stream and makes sure it
is a byte array.
|
BEValue |
bdecodeList()
Returns the next bencoded value on the stream and makes sure it
is a list.
|
BEValue |
bdecodeMap()
Returns the next bencoded value on the stream and makes sure it
is a map (dictonary).
|
BEValue |
bdecodeNumber()
Returns the next bencoded value on the stream and makes sure it
is a number.
|
byte[] |
get_special_map_digest()
Ugly hack.
|
int |
getNextIndicator()
Returns what the next bencoded object will be on the stream or -1
when the end of stream has been reached.
|
static void |
main(String[] args)
prints out the decoded data
