```
public class BDecoder
extends java.lang.Object
```
Decodes a bencoded stream to BEValues. 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).

修飾子とタイプ	メソッド	説明
`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(java.io.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(java.lang.String[] args)`	prints out the decoded data

  - BDecoder
```
public BDecoder(java.io.InputStream in)
```
    Initalizes a new BDecoder. Nothing is read from the given InputStream yet.
- メソッドの詳細
  - get_special_map_digest
```
public byte[] get_special_map_digest()
```
    Ugly hack. Return the SHA has over bytes that make up the special map.
    
    戻り値:
    
    null if there was no special map
  - bdecode
```
public static BEValue bdecode(java.io.InputStream in)
                       throws java.io.IOException
```
    Creates a new BDecoder and immediatly decodes the first value it sees.
    
    戻り値:
    
    The first BEValue on the stream or null when the stream has ended.
    
    例外:
    
    InvalidBEncodingException - when the stream doesn't start with a bencoded value or the stream isn't a bencoded stream at all.
    
    java.io.IOException - when somthing bad happens with the stream to read from.
  - getNextIndicator
```
public int getNextIndicator()
                     throws java.io.IOException
```
    Returns what the next bencoded object will be on the stream or -1 when the end of stream has been reached. Can return something unexpected (not '0' .. '9', 'i', 'l' or 'd') when the stream isn't bencoded. This might or might not read one extra byte from the stream.
    
    例外:
    
    java.io.IOException
  - bdecode
```
public BEValue bdecode()
                throws java.io.IOException
```
    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.
    
    例外:
    
    java.io.IOException
  - bdecodeBytes
```
public BEValue bdecodeBytes()
                     throws java.io.IOException
```
    Returns the next bencoded value on the stream and makes sure it is a byte array. If it is not a bencoded byte array it will throw InvalidBEncodingException.
    
    例外:
    
    java.io.IOException
  - bdecodeNumber
```
public BEValue bdecodeNumber()
                      throws java.io.IOException
```
    Returns the next bencoded value on the stream and makes sure it is a number. If it is not a number it will throw InvalidBEncodingException.
    
    例外:
    
    java.io.IOException
  - bdecodeList
```
public BEValue bdecodeList()
                    throws java.io.IOException
```
    Returns the next bencoded value on the stream and makes sure it is a list. If it is not a list it will throw InvalidBEncodingException.
    
    例外:
    
    java.io.IOException
  - bdecodeMap
```
public BEValue bdecodeMap()
                   throws java.io.IOException
```
    Returns the next bencoded value on the stream and makes sure it is a map (dictonary). If it is not a map it will throw InvalidBEncodingException.
    
    例外:
    
    java.io.IOException
  - main
```
public static void main(java.lang.String[] args)
```
    prints out the decoded data
