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]

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]
