java.lang.Objectjava.io.InputStream
org.apache.http.impl.io.ChunkedInputStream
public class ChunkedInputStream
Implements chunked transfer coding. See RFC 2616, section 3.6.1. It transparently coalesces chunks of a HTTP stream that uses chunked transfer coding. After the stream is read to the end, it provides access to the trailers, if any.
Note that this class NEVER closes the underlying stream, even when close gets called. Instead, it will read until the "end" of its chunking on close, which allows for the seamless execution of subsequent HTTP 1.1 requests, while not requiring the client to remember to read the entire contents of the response.

close()
Upon close, this reads the remainder of the chunked message, leaving the underlying socket at a position to start reading the next response without scanning. |

public int read() throws java.io.IOException
Returns all the data in a chunked stream in coalesced form. A chunk is followed by a CRLF. The method returns -1 as soon as a chunksize of 0 is detected.
Trailer headers are read automcatically at the end of the stream and can be obtained with the getResponseFooters() method.
