Destroys the encoding.

| const TextEncoding::CharacterMap & Poco::ASCIIEncoding::characterMap | ( | ) | const [virtual] |
Returns true if the given name is one of the names of this encoding. For example, the "ISO-8859-1" encoding is also known as "Latin-1".
Encoding name comparision are be case insensitive.

The convert function is used to convert multibyte sequences; bytes will point to a byte sequence of n bytes where getCharacterMap()[*bytes] == -n.
The convert function must return the Unicode scalar value represented by this byte sequence or -1 if the byte sequence is malformed. The default implementation returns (int) bytes[0].

| int Poco::ASCIIEncoding::convert | ( | const unsigned char * | bytes | ) | const [virtual] |
Returns the CharacterMap for the encoding. The CharacterMap should be kept in a static member. As characterMap() can be called frequently, it should be implemented in such a way that it just returns a static map. If the map is built at runtime, this should be done in the constructor.

| bool Poco::ASCIIEncoding::isA | ( | const std::string & | encodingName | ) | const [virtual] |
Returns the canonical name of this encoding, e.g. "ISO-8859-1". Encoding name comparisons are case insensitive.
