Constructor Detail

ChunkedInputStream

public ChunkedInputStream(java.io.InputStream stream)

Constructs a chunked input stream wrapping input.

Parameters:

stream - Must be non-null.

Method Detail

close

public void close()
           throws java.io.IOException

Closes the underlying input stream.

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.InputStream

Throws:

java.io.IOException

read

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

Reads up to len bytes of data from the input stream into an array of bytes. An attempt is made to read as many as len bytes, but a smaller number may be read, possibly zero. The number of bytes actually read is returned as an integer.

Overrides:

read in class java.io.InputStream

Parameters:

b - The buffer into which the data is read

off - The start offset into array b at which the data is written

len - The maximum number of bytes to read

Throws:

java.io.IOException - if an input/output error occurs

read

public int read()
         throws java.io.IOException

Reads and return a single byte from this input stream, or -1 if end of file has been encountered.

Specified by:

read in class java.io.InputStream

Throws:

java.io.IOException - if an input/output error occurs

getEntityHeaders

public MessageHeaders getEntityHeaders()

Returns "trailer" entity headers, which appear at the end of a chunked encoding request. Returns null if not at the end of input. These will only appear when isEndChunk() returns true. See: http://www.w3.org/Protocols/rfc2616/rfc2616-sec3.html#sec3.6.1

isEndChunk

public boolean isEndChunk()

Returns true if the end chunk was read.

toString

public java.lang.String toString()

Returns a debug string.

Overrides:

toString in class java.lang.Object
