Member Function Documentation

const char * Poco::ASCIIEncoding::canonicalName (  )  const [virtual]

Destroys the encoding.

Implements Poco::TextEncoding.

Definition at line 80 of file ASCIIEncoding.cpp.

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.

Implements Poco::TextEncoding.

Definition at line 97 of file ASCIIEncoding.cpp.

int Poco::ASCIIEncoding::convert ( int  ch,
unsigned char *  bytes,
int  length 
) const [virtual]

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].

Reimplemented from Poco::TextEncoding.

Definition at line 109 of file ASCIIEncoding.cpp.

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.

Reimplemented from Poco::TextEncoding.

Definition at line 103 of file ASCIIEncoding.cpp.

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.

Implements Poco::TextEncoding.

Definition at line 86 of file ASCIIEncoding.cpp.
