Constructor Detail

SimpleSingleByteEncoding

public SimpleSingleByteEncoding(java.lang.String name)
Main constructor.

Parameters:
name - the encoding's name
Method Detail

getName

public java.lang.String getName()
Returns the encoding's name.

Specified by:
getName in interface SingleByteEncoding
Returns:
the name of the encoding

mapChar

public char mapChar(char c)
Maps a Unicode character to a code point in the encoding.

Specified by:
mapChar in interface SingleByteEncoding
Parameters:
c - the Unicode character to map
Returns:
the code point in the encoding or 0 (=.notdef) if not found

getCharNameMap

public java.lang.String[] getCharNameMap()
Returns the array of character names for this encoding.

Specified by:
getCharNameMap in interface SingleByteEncoding
Returns:
the array of character names (unmapped code points are represented by a ".notdef" value)

getFirstChar

public int getFirstChar()
Returns the index of the first defined character.

Returns:
the index of the first defined character (always 1 for this class)

getLastChar

public int getLastChar()
Returns the index of the last defined character.

Returns:
the index of the last defined character

getSize

public int getSize()
Returns the number of characters defined by this encoding.

Returns:
the number of characters

isFull

public boolean isFull()
Indicates whether the encoding is full (with 256 code points).

Returns:
true if the encoding is full

addCharacter

public char addCharacter(NamedCharacter ch)
Adds a new character to the encoding.

Parameters:
ch - the named character
Returns:
the code point assigned to the character

getCharacterForIndex

public NamedCharacter getCharacterForIndex(int codePoint)
Returns the named character at a given code point in the encoding.

Parameters:
codePoint - the code point of the character
Returns:
the NamedCharacter (or null if no character is at this position)

getUnicodeCharMap

public char[] getUnicodeCharMap()
Returns a character array with Unicode scalar values which can be used to map encoding code points to Unicode values. Note that this does not return all possible Unicode values that the encoding maps.

Specified by:
getUnicodeCharMap in interface SingleByteEncoding
Returns:
a character array with Unicode scalar values

toString

public java.lang.String toString()

Overrides:
toString in class java.lang.Object
