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.

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. Reimplemented 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. Reimplemented 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. Reimplemented 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. Reimplemented in ACEXML_FileCharStream, ACEXML_HttpCharStream, and ACEXML_StrCharStream.

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

Read the next batch of ACEXML_Char strings. Reimplemented in ACEXML_FileCharStream, ACEXML_HttpCharStream, and ACEXML_StrCharStream.
