public abstract class TokenMarker
extends Object
```
A token marker that splits lines of text into tokens. Each token carries a length field and an indentification tag that can be mapped to a color for painting that token.

For performance reasons, the linked list of tokens is reused after each line is tokenized. Therefore, the return value of markTokens should only be used for immediate painting. Notably, it cannot be cached.

- Field Detail
  - firstToken
```
protected Token firstToken
```
    The first token in the list. This should be used as the return value from markTokens().
  - lastToken
```
protected Token lastToken
```
    The last token in the list. New tokens are added here. This should be set to null before a new line is to be tokenized.
  - lineInfo
```
protected TokenMarker.LineInfo[] lineInfo
```
    An array for storing information about lines. It is enlarged and shrunk automatically by the insertLines() and deleteLines() methods.
  - length
```
protected int length
```
    The number of lines in the model being tokenized. This can be less than the length of the lineInfo array.
  - lastLine
```
protected int lastLine
```
    The last tokenized line.
  - nextLineRequested
```
protected boolean nextLineRequested
```
    True if the next line should be painted.
- Constructor Detail
  - TokenMarker
```
protected TokenMarker()
```
    Creates a new TokenMarker. This DOES NOT create a lineInfo array; an initial call to insertLines() does that.
- Method Detail
  - markTokens
```
public Token markTokens(Segment line,
                        int lineIndex)
```
    A wrapper for the lower-level markTokensImpl method that is called to split a line up into tokens.
    
    Parameters:
    
    line - The line
    
    lineIndex - The line number
  - markTokensImpl
```
protected abstract byte markTokensImpl(byte token,
                                       Segment line,
                                       int lineIndex)
```
    An abstract method that splits a line up into tokens. It should parse the line, and call addToken() to add syntax tokens to the token list. Then, it should return the initial token type for the next line.
    
    For example if the current line contains the start of a multiline comment that doesn't end on that line, this method should return the comment token type so that it continues on the next line.
    
    Parameters:
    
    token - The initial token type for this line
    
    line - The line to be tokenized
    
    lineIndex - The index of the line in the document, starting at 0
    
    Returns:
    
    The initial token type for the next line
  - supportsMultilineTokens
```
public boolean supportsMultilineTokens()
```
    Returns if the token marker supports tokens that span multiple lines. If this is true, the object using this token marker is required to pass all lines in the document to the markTokens() method (in turn).
    
    The default implementation returns true; it should be overridden to return false on simpler token markers for increased speed.
  - insertLines
```
public void insertLines(int index,
                        int lines)
```
    Informs the token marker that lines have been inserted into the document. This inserts a gap in the lineInfo array.
    
    Parameters:
    
    index - The first line number
    
    lines - The number of lines
  - deleteLines
```
public void deleteLines(int index,
                        int lines)
```
    Informs the token marker that line have been deleted from the document. This removes the lines in question from the lineInfo array.
    
    Parameters:
    
    index - The first line number
    
    lines - The number of lines
  - getLineCount
```
public int getLineCount()
```
    Returns the number of lines in this token marker.
  - isNextLineRequested
```
public boolean isNextLineRequested()
```
    Returns true if the next line should be repainted. This will return true after a line has been tokenized that starts a multiline token that continues onto the next line.
  - ensureCapacity
```
protected void ensureCapacity(int index)
```
    Ensures that the lineInfo array can contain the specified index. This enlarges it if necessary. No action is taken if the array is large enough already.
    
    It should be unnecessary to call this under normal circumstances; insertLine() should take care of enlarging the line info array automatically.
    
    Parameters:
    
    index - The array index
  - addToken
```
protected void addToken(int length,
                        byte id)
```
    Adds a token to the token list.
    
    Parameters:
    
    length - The length of the token
    
    id - The id of the token
