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_HttpCharStream, ACEXML_FileCharStream, and ACEXML_StrCharStream.

virtual int ACEXML_CharStream::close

(

void

)

[pure virtual]

Close this stream and release all resources used by it.

Implemented in ACEXML_HttpCharStream, ACEXML_FileCharStream, 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_StrCharStream, ACEXML_HttpCharStream, and ACEXML_FileCharStream.

virtual const ACEXML_Char* ACEXML_CharStream::getEncoding

(

void

)

[pure virtual]

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_StrCharStream, ACEXML_FileCharStream, 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.
