Member Function Documentation

int ACEXML_HttpCharStream::available (  void    )  [virtual]

Returns the available ACEXML_Char in the buffer. -1 if the object is not initialized properly. Reimplemented from ACEXML_CharStream.

int ACEXML_HttpCharStream::close (  void    )  [virtual]

Close this stream and release all resources used by it. Reimplemented from ACEXML_CharStream.

int ACEXML_HttpCharStream::get (  ACEXML_Char &    ch )  [virtual]

Read the next ACEXML_Char. Return -1 if we are not able to return an ACEXML_Char, 0 if EOS is reached, or 1 if succeed. Reimplemented from ACEXML_CharStream.

int ACEXML_HttpCharStream::get_url (  size_t &    len )  [private]

Fetch the URL and save it in backing store.

int ACEXML_HttpCharStream::open (  const ACEXML_Char *    url )

Open an URL.

int ACEXML_HttpCharStream::peek (  void    )  [virtual]

Peek the next ACEXML_Char in the CharStream. Return the character if succeess, -1 if EOS is reached. Reimplemented from ACEXML_CharStream.

int ACEXML_HttpCharStream::read (  ACEXML_Char *    str, size_t    len )  [virtual]

Read the next batch of ACEXML_Char strings. Reimplemented from ACEXML_CharStream.

int ACEXML_HttpCharStream::send_request (  void    )  [private]

Send a HTTP/1.1 request to fetch the contents of the URL.
