## 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.

## Constructor & Destructor Documentation

ACEXML_CharStream::~ACEXML_CharStream | ( | void |  | ) | `[pure virtual]`

| Virtual destructor, must have.

## 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.

virtual int ACEXML_CharStream::close | ( | void |  | ) | `[pure virtual]`

| Close this stream and release all resources used by it. Reimplemented in ACEXML_FileCharStream.

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.

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.

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.
