Method Detail

### getCharIndex

    int getCharIndex(int bytePos)

  Calculates the char index of the given byte index. Look forward if index is not in table

  Parameters:
    `bytePos` - The character offset to check
  Returns:
    the char index

### getCharIndex

    int getCharIndex(int bytePos,
                     int startCP)

  Calculates the char index of the given byte index. Look forward if index is not in table

  Parameters:
    `bytePos` - The character offset to check
    `startCP` - look from this characted position
  Returns:
    the char index

### isIndexInTable

    boolean isIndexInTable(int bytePos)

  Check if index is in table

  Parameters:
    `bytePos` -
  Returns:
    true if index in table, false if not

### lookIndexForward

    int lookIndexForward(int bytePos)

  Return first index >= bytePos that is in table

  Parameters:
    `bytePos` -
  Returns:
    first index greater or equal to bytePos that is in table

### lookIndexBackward

    int lookIndexBackward(int bytePos)

  Return last index <= bytePos that is in table

  Parameters:
    `bytePos` -
  Returns:
    last index less of equal to bytePos that is in table
