- Method Detail
  - isEndOfInput
```
boolean isEndOfInput()
              throws Exception
```
    Return true if and only if there is no data left in the stream and the stream has reached at its end.
    
    Throws:
    
    Exception
  - readChunk
```
B readChunk(BufferAllocator allocator)
     throws Exception
```
    Fetches a chunked data from the stream. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent isEndOfInput() call must return true.
    
    Parameters:
    
    allocator - BufferAllocator if buffer allocation is necessary.
    
    Returns:
    
    the fetched chunk. null if there is no data left in the stream. Please note that null does not necessarily mean that the stream has reached at its end. In a slow stream, the next chunk might be unavailable just momentarily.
    
    Throws:
    
    Exception
  - length
```
long length()
```
    Returns the length of the input.
    
    Returns:
    
    the length of the input if the length of the input is known. a negative value if the length of the input is unknown.
  - progress
```
long progress()
```
    Returns current transfer progress.
