public class HttpInputStream

extends java.io.FilterInputStream

HTTP Chunking InputStream. This FilterInputStream acts as a BufferedInputStream until setChunking(true) is called. Once chunking is enabled, the raw stream is chunk decoded as per RFC2616. The "8859-1" encoding is used on underlying LineInput instance for line based reads from the raw stream. This class is not synchronized and should be synchronized explicitly if an instance is used by multiple threads.

Constructor Detail

HttpInputStream

public HttpInputStream(java.io.InputStream in)

Constructor.

---

HttpInputStream

public HttpInputStream(java.io.InputStream in,
                       int bufferSize)

Constructor.

Method Detail

getInputStream

public java.io.InputStream getInputStream()

Get the raw stream. A stream without filters or chunking is returned. This stream may still be buffered and uprocessed bytes may be in the buffer.

---

getFilterStream

public java.io.InputStream getFilterStream()

Get Filter InputStream. Get the current top of the InputStream filter stack

---

setFilterStream

public void setFilterStream(java.io.InputStream filter)

Set Filter InputStream. Set input filter stream, which should be constructed to wrap the stream returned from get FilterStream.

---

isChunking

public boolean isChunking()

Get chunking mode

---

setChunking

public void setChunking()
                 throws java.lang.IllegalStateException

Set chunking mode. Chunking can only be turned off with a call to resetStream().

---

resetStream

public void resetStream()
                 throws java.lang.IllegalStateException

Reset the stream. Turn chunking off and disable all filters.

---

close

public void close()
           throws java.io.IOException

Description copied from class: java.io.FilterInputStream

This method closes the input stream by closing the input stream that this object is filtering. Future attempts to access this stream may throw an exception.

---

setContentLength

public void setContentLength(int len)

Set the content length. Only this number of bytes can be read before EOF is returned.

---

getContentLength

public int getContentLength()

Get the content length.

---

getTrailer

public HttpFields getTrailer()

---

destroy

public void destroy()

---
