public class ChunkedInputStream
extends java.io.InputStream

Implements chunked transfer coding. The content is received in small chunks. Entities transferred using this input stream can be of unlimited length. 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.

构造器详细资料

ChunkedInputStream

public ChunkedInputStream(SessionInputBuffer in)

Wraps session input stream and reads chunk coded input.

参数:

in - The session input buffer

方法详细资料

available

public int available()
              throws java.io.IOException

覆盖:

available 在类中 java.io.InputStream

抛出:

java.io.IOException

read

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 automatically at the end of the stream and can be obtained with the getResponseFooters() method.

指定者:

read 在类中 java.io.InputStream

返回:

-1 of the end of the stream has been reached or the next data byte

抛出:

java.io.IOException - in case of an I/O error

read

public int read(byte[] b,
       int off,
       int len)
         throws java.io.IOException

Read some bytes from the stream.

覆盖:

read 在类中 java.io.InputStream

参数:

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.

返回:

The number of bytes returned or -1 if the end of stream has been reached.

抛出:

java.io.IOException - in case of an I/O error

read

public int read(byte[] b)
         throws java.io.IOException

Read some bytes from the stream.

覆盖:

read 在类中 java.io.InputStream

参数:

b - The byte array that will hold the contents from the stream.

返回:

The number of bytes returned or -1 if the end of stream has been reached.

抛出:

java.io.IOException - in case of an I/O error

close

public void close()
           throws java.io.IOException

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.

指定者:

close 在接口中 java.io.Closeable

指定者:

close 在接口中 java.lang.AutoCloseable

覆盖:

close 在类中 java.io.InputStream

抛出:

java.io.IOException - in case of an I/O error

getFooters

public Header[] getFooters()
