Method Detail

readRawLine

public static byte[] readRawLine(InputStream inputStream)
                          throws IOException
Return byte array from an (unchunked) input stream. Stop reading when "\n" terminator encountered If the stream ends before the line terminator is found, the last part of the string will still be returned. If no input data available, null is returned.

Parameters:
inputStream - the stream to read from
Returns:
a byte array from the stream
Throws:
IOException - if an I/O problem occurs

readLine

public static String readLine(InputStream inputStream,
                              String charset)
                       throws IOException
Read up to "\n" from an (unchunked) input stream. If the stream ends before the line terminator is found, the last part of the string will still be returned. If no input data available, null is returned.

Parameters:
inputStream - the stream to read from
charset - charset of HTTP protocol elements
Returns:
a line from the stream
Throws:
IOException - if an I/O problem occurs
Since:
3.0

readLine

public static String readLine(InputStream inputStream)
                       throws IOException
Deprecated. use #readLine(InputStream, String)

Read up to "\n" from an (unchunked) input stream. If the stream ends before the line terminator is found, the last part of the string will still be returned. If no input data available, null is returned

Parameters:
inputStream - the stream to read from
Returns:
a line from the stream
Throws:
IOException - if an I/O problem occurs

parseHeaders

public static Header[] parseHeaders(InputStream is,
                                    String charset)
                             throws IOException,
                                    HttpException
Parses headers from the given stream. Headers with the same name are not combined.

Parameters:
is - the stream to read headers from
charset - the charset to use for reading the data
Returns:
an array of headers in the order in which they were parsed
Throws:
IOException - if an IO error occurs while reading from the stream
HttpException - if there is an error parsing a header value
Since:
3.0

parseHeaders

public static Header[] parseHeaders(InputStream is)
                             throws IOException,
                                    HttpException
Deprecated. use #parseHeaders(InputStream, String)

Parses headers from the given stream. Headers with the same name are not combined.

Parameters:
is - the stream to read headers from
Returns:
an array of headers in the order in which they were parsed
Throws:
IOException - if an IO error occurs while reading from the stream
HttpException - if there is an error parsing a header value
