## Constructor & Destructor Documentation

ACEXML_HttpCharStream::ACEXML_HttpCharStream | ( | void |  | ) |

| Default constructor.

ACEXML_HttpCharStream::~ACEXML_HttpCharStream | ( | void |  | ) | `[virtual]`

| Destructor.

## 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]`

| Close this stream and release all resources used by it. 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. Implements ACEXML_CharStream.

int ACEXML_HttpCharStream::get_url | ( | size_t & | len | ) | `[private]`

| Fetch the URL and save it in backing store.

const ACEXML_Char * ACEXML_HttpCharStream::getEncoding | ( | void |  | ) | `[virtual]`

| Get the encoding of the file Implements ACEXML_CharStream.

const ACEXML_Char * ACEXML_HttpCharStream::getSystemId | ( | void |  | ) | `[virtual]`

| Implements ACEXML_CharStream.

int ACEXML_HttpCharStream::open | ( | const ACEXML_Char * | url | ) |

| Open an URL.

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. Implements ACEXML_CharStream.

int ACEXML_HttpCharStream::send_request | ( | void |  | ) | `[private]`

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