Class SimpleSingleByteEncoding

java.lang.Object
org.apache.fop.fonts.SimpleSingleByteEncoding
All Implemented Interfaces:
SingleByteEncoding
public class SimpleSingleByteEncoding extends Object implements SingleByteEncoding
A simple implementation of the OneByteEncoding mostly used for encodings that are constructed on-the-fly.

  • Constructor Details

    • SimpleSingleByteEncoding

      public SimpleSingleByteEncoding(String name)
      Main constructor.
      Parameters:
      name - the encoding's name

  • Method Details

    • getName

      public 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 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 String toString()
      Overrides:
      toString in class Object
