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.

Implements ACEXML_CharStream.

int ACEXML_HttpCharStream::close ( void  )

virtual

Close this stream and release all resources used by it.

Implements ACEXML_CharStream.

int ACEXML_HttpCharStream::determine_encoding ( void  )

virtual

Determine the encoding of the file.

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.

Implements ACEXML_CharStream.

int ACEXML_HttpCharStream::get_url ( size_t &  len )

private

Fetch the URL and save it in backing store.

const ACEXML_Char * ACEXML_HttpCharStream::getEncoding ( void  )

virtual

Get the encoding of the file

Implements ACEXML_CharStream.

const ACEXML_Char * ACEXML_HttpCharStream::getSystemId ( void  )

virtual

Implements ACEXML_CharStream.

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.

Implements ACEXML_CharStream.

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

virtual

Read the next batch of ACEXML_Char strings

Implements ACEXML_CharStream.

void ACEXML_HttpCharStream::rewind ( void  )

virtual

Resets the file pointer to the beginning of the stream.

Implements ACEXML_CharStream.

int ACEXML_HttpCharStream::send_request ( void  )

private

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