org.vishia.charset

Class ISO8859_1

java.lang.Object

org.vishia.charset.ISO8859_1

All Implemented Interfaces:

CodeCharset

public class ISO8859_1
extends java.lang.Object
implements CodeCharset

Classes to convert UTF-16 to 8-bit-codings. The implementation of Charset etc. may be over engineered, An important feature: report non-map-able characters, is missing. The conversion between the ISO-8859-1 code page and UTF16 is very simple because it is the low part of UTF-16. All other code pages needs three tables with binary search for encoding, see ISO8859_2 etc.

getCode

public int getCode(char cc)

Description copied from interface: CodeCharset

Specified by:

getCode in interface CodeCharset

Parameters:

cc - the character

Parameters:

code - in range 0..255, maybe >= 256 for UTF-8 sequences (The lowest byte is the first byte), with max. 4 Byte (for not all UTF characters)

Returns:

The character.
