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]

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.

int ACEXML_HttpCharStream::peek

(

void

)

[virtual]

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

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.
