Detailed Description

ACEXML_CharStream is an abstract class (interface) which defines the basic opertions a parser could use to retrieve XML charater sequence. The sequence can be read from a file or a character buffer.

Constructor & Destructor Documentation

ACEXML_CharStream::~ACEXML_CharStream ( void  )

pure virtual

Virtual destructor, must have.

Member Function Documentation

virtual int ACEXML_CharStream::available ( void  )

pure virtual

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

Implemented in ACEXML_FileCharStream, ACEXML_HttpCharStream, and ACEXML_StrCharStream.

virtual int ACEXML_CharStream::close ( void  )

pure virtual

Close this stream and release all resources used by it.

Implemented in ACEXML_FileCharStream, ACEXML_HttpCharStream, and ACEXML_StrCharStream.

virtual int ACEXML_CharStream::get ( ACEXML_Char &  ch )

pure 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.

Implemented in ACEXML_FileCharStream, ACEXML_StrCharStream, and ACEXML_HttpCharStream.

virtual const ACEXML_Char* ACEXML_CharStream::getEncoding ( void  )

pure virtual

Implemented in ACEXML_FileCharStream, ACEXML_HttpCharStream, and ACEXML_StrCharStream.

virtual const ACEXML_Char* ACEXML_CharStream::getSystemId ( void  )

pure virtual

Implemented in ACEXML_FileCharStream, ACEXML_HttpCharStream, and ACEXML_StrCharStream.

virtual int ACEXML_CharStream::peek ( void  )

pure virtual

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

Implemented in ACEXML_FileCharStream, ACEXML_StrCharStream, and ACEXML_HttpCharStream.

virtual int ACEXML_CharStream::read ( ACEXML_Char *  str, size_t  len  )

pure virtual

Read the next batch of ACEXML_Char strings

Implemented in ACEXML_FileCharStream, ACEXML_StrCharStream, and ACEXML_HttpCharStream.

virtual void ACEXML_CharStream::rewind ( void  )

pure virtual

Resets the pointer to the beginning of the stream.

Implemented in ACEXML_StrCharStream, ACEXML_FileCharStream, and ACEXML_HttpCharStream.
