org.apache.fop.fonts.AbstractCodePointMapping
public class AbstractCodePointMapping
extends java.lang.Object
Abstract base class for code point mapping classes (1-byte character encodings).
protected void | buildFromTable(int[] table) - Builds the internal lookup structures based on a given table.
|
String[] | getCharNameMap() - Returns the array of character names for this encoding.
|
short | getCodePointForGlyph(String charName) - Returns the index of a character/glyph with the given name.
|
String | getName() - Returns the encoding's name.
|
char[] | getUnicodeCharMap() - Returns a character array with Unicode scalar values which can be used to map encoding
code points to Unicode values.
|
char | getUnicodeForIndex(int idx) - Returns the main Unicode value that is associated with the given code point in the encoding.
|
char | mapChar(char c) - Maps a Unicode character to a code point in the encoding.

AbstractCodePointMapping
public AbstractCodePointMapping(String name,
int[] table)
Main constructor.
name
- the name of the encodingtable
- the table ([code point, unicode scalar value]+) with the mapping
AbstractCodePointMapping
public AbstractCodePointMapping(String name,
int[] table,
String[] charNameMap)
Extended constructor.
name
- the name of the encodingtable
- the table ([code point, unicode scalar value]+) with the mappingcharNameMap
- all character names in the encoding (a value of null will be converted
to ".notdef")
buildFromTable
protected void buildFromTable(int[] table)
Builds the internal lookup structures based on a given table.
table
- the table ([code point, unicode scalar value]+) with the mapping
getCharNameMap
public String[] getCharNameMap()
Returns the array of character names for this encoding.
- the array of character names
(unmapped code points are represented by a ".notdef" value)
getCodePointForGlyph
public short getCodePointForGlyph(String charName)
Returns the index of a character/glyph with the given name. Note that this
method is relatively slow and should only be used for fallback operations.
charName
- the character name
- the index of the character in the encoding or -1 if it doesn't exist
getName
public String getName()
Returns the encoding's name.
getUnicodeCharMap
public final 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.
- a character array with Unicode scalar values
getUnicodeForIndex
public final char getUnicodeForIndex(int idx)
Returns the main Unicode value that is associated with the given code point in the encoding.
Note that multiple Unicode values can theoretically be mapped to one code point in the
encoding.
idx
- the code point in the encoding
- the Unicode value (or \uFFFF (NOT A CHARACTER) if no Unicode value is at that point)
mapChar
public final char mapChar(char c)
Maps a Unicode character to a code point in the encoding.
c
- the Unicode character to map
- the coid point in the encoding or 0 (=.notdef) if not found
toString
public String toString()
