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.

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.
