ChunkedInputStream

extends InputStream
java.lang.Object
   ↳ java.io.InputStream
     ↳ org.apache.http.impl.io.ChunkedInputStream

Class Overview

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.

Summary

Public Constructors
ChunkedInputStream(SessionInputBuffer in)
Public Methods
void 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.
Header[] getFooters()
int read(byte[] b, int off, int len)
Read some bytes from the stream.
int read(byte[] b)
Read some bytes from the stream.
int read()

Returns all the data in a chunked stream in coalesced form.

Public Methods

public void close ()

Since: API Level 1

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.

Throws
IOException If an IO problem occurs.

public Header[] getFooters ()

Since: API Level 1

public int read (byte[] b, int off, int len)

Since: API Level 1

Read some bytes from the stream.

Parameters
b The byte array that will hold the contents from the stream.
off The offset into the byte array at which bytes will start to be placed.
len the maximum number of bytes that can be returned.
Returns
  • The number of bytes returned or -1 if the end of stream has been reached.
Throws
IOException if an IO problem occurs.

public int read (byte[] b)

Since: API Level 1

Read some bytes from the stream.

Parameters
b The byte array that will hold the contents from the stream.
Returns
  • The number of bytes returned or -1 if the end of stream has been reached.
Throws
IOException if an IO problem occurs.

public int read ()

Since: API Level 1

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.

Returns
  • -1 of the end of the stream has been reached or the next data byte
Throws
IOException If an IO problem occurs
