ACEXML_HttpCharStream()

ACEXML_HttpCharStream::ACEXML_HttpCharStream

(

)

Default constructor.

~ACEXML_HttpCharStream()

ACEXML_HttpCharStream::~ACEXML_HttpCharStream ( )

virtual

Destructor.

Member Function Documentation

available()

int ACEXML_HttpCharStream::available ( )

virtual

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

Implements ACEXML_CharStream.

close()

int ACEXML_HttpCharStream::close ( )

virtual

Close this stream and release all resources used by it.

Implements ACEXML_CharStream.

determine_encoding()

int ACEXML_HttpCharStream::determine_encoding ( )

virtual

Determine the encoding of the file.

get()

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.

get_url()

int ACEXML_HttpCharStream::get_url ( size_t &  len )

private

Fetch the URL and save it in backing store.

getEncoding()

const ACEXML_Char * ACEXML_HttpCharStream::getEncoding ( )

virtual

Get the encoding of the file

Implements ACEXML_CharStream.

getSystemId()

const ACEXML_Char * ACEXML_HttpCharStream::getSystemId ( )

virtual

Implements ACEXML_CharStream.

open()

int ACEXML_HttpCharStream::open

(

const ACEXML_Char *

url

)

Open an URL.

peek()

int ACEXML_HttpCharStream::peek ( )

virtual

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

Implements ACEXML_CharStream.

read()

int ACEXML_HttpCharStream::read ( ACEXML_Char *  str, size_t  len  )

virtual

Read the next batch of ACEXML_Char strings

Implements ACEXML_CharStream.

rewind()

void ACEXML_HttpCharStream::rewind ( )

virtual

Resets the file pointer to the beginning of the stream.

Implements ACEXML_CharStream.

send_request()

int ACEXML_HttpCharStream::send_request ( )

private

Send a HTTP/1.1 request to fetch the contents of the URL.
