Methods Summary

Methods
Type Params	Return Type	Name and description
	`Reduction`	`asReduction()` Creates a `Reduction` from this token.
	`Reduction`	`asReduction(CSTNode second)` Creates a `Reduction` from this token, adding the supplied node as the second element.
	`Reduction`	`asReduction(CSTNode second, CSTNode third)` Creates a `Reduction` from this token, adding the supplied nodes as the second and third element, respectively.
	`Reduction`	`asReduction(CSTNode second, CSTNode third, CSTNode fourth)` Creates a `Reduction` from this token, adding the supplied nodes as the second, third, and fourth element, respectively.
	`Token`	`dup()` Returns a copy of this Token.
	`CSTNode`	`get(int index)` Returns the specified element, or null.
	`int`	`getMeaning()` Returns the meaning of this node.
	`Token`	`getRoot()` Returns the root of the node.
	`String`	`getRootText()` Returns the text of the root node.
	`int`	`getStartColumn()` Returns the starting column of the node.
	`int`	`getStartLine()` Returns the starting line of the node.
	`String`	`getText()` Returns the text of the token.
	`int`	`getType()` Returns the actual type of the node.
	`static Token`	`newDecimal(String text, int startLine, int startColumn)` Creates a token that represents a decimal number.
	`static Token`	`newIdentifier(String text, int startLine, int startColumn)` Creates a token that represents an identifier.
	`static Token`	`newInteger(String text, int startLine, int startColumn)` Creates a token that represents an integer.
	`static Token`	`newKeyword(String text, int startLine, int startColumn)` Creates a token that represents a keyword.
	`static Token`	`newPlaceholder(int type)` Creates a token with the specified meaning.
	`static Token`	`newString(String text, int startLine, int startColumn)` Creates a token that represents a double-quoted string.
	`static Token`	`newSymbol(int type, int startLine, int startColumn)` Creates a token that represents a symbol, using a library for the text.
	`static Token`	`newSymbol(String type, int startLine, int startColumn)` Creates a token that represents a symbol, using a library for the type.
	`CSTNode`	`setMeaning(int meaning)` Sets the meaning for this node (and it's root Token).
	`void`	`setText(String text)` Not advisable, but if you need to adjust the token's text, this will do it.
	`int`	`size()` Returns the number of elements in the node (including root).

- Field Detail
  - public static final Token EOF
  - public static final Token NULL
- Constructor Detail
  - public Token(int type, String text, int startLine, int startColumn)
    
    Initializes the Token with the specified information.
- Method Detail
  - public Reduction asReduction()
    
    Creates a Reduction from this token. Returns self if the node is already a Reduction.
  - public Reduction asReduction(CSTNode second)
    
    Creates a Reduction from this token, adding the supplied node as the second element.
  - public Reduction asReduction(CSTNode second, CSTNode third)
    
    Creates a Reduction from this token, adding the supplied nodes as the second and third element, respectively.
  - public Reduction asReduction(CSTNode second, CSTNode third, CSTNode fourth)
    
    Creates a Reduction from this token, adding the supplied nodes as the second, third, and fourth element, respectively.
  - public Token dup()
    
    Returns a copy of this Token.
  - public CSTNode get(int index)
    
    Returns the specified element, or null.
  - public int getMeaning()
    
    Returns the meaning of this node. If the node isEmpty(), returns the type of Token.NULL.
  - public Token getRoot()
    
    Returns the root of the node. By convention, all nodes have a Token as the first element (or root), which indicates the type of the node. May return null if the node isEmpty().
  - public String getRootText()
    
    Returns the text of the root node. Uses getRoot(true) to get the root, so you will only receive null in return if the root token returns it.
  - public int getStartColumn()
    
    Returns the starting column of the node. Returns -1 if not known.
  - public int getStartLine()
    
    Returns the starting line of the node. Returns -1 if not known.
  - public String getText()
    
    Returns the text of the token. Equivalent to getRootText() when called directly.
  - public int getType()
    
    Returns the actual type of the node. If the node isEmpty(), returns the type of Token.NULL.
  - public static Token newDecimal(String text, int startLine, int startColumn)
    
    Creates a token that represents a decimal number.
  - public static Token newIdentifier(String text, int startLine, int startColumn)
    
    Creates a token that represents an identifier.
  - public static Token newInteger(String text, int startLine, int startColumn)
    
    Creates a token that represents an integer.
  - public static Token newKeyword(String text, int startLine, int startColumn)
    
    Creates a token that represents a keyword. Returns null if the specified text isn't a keyword.
  - public static Token newPlaceholder(int type)
    
    Creates a token with the specified meaning.
  - public static Token newString(String text, int startLine, int startColumn)
    
    Creates a token that represents a double-quoted string.
  - public static Token newSymbol(int type, int startLine, int startColumn)
    
    Creates a token that represents a symbol, using a library for the text.
  - public static Token newSymbol(String type, int startLine, int startColumn)
    
    Creates a token that represents a symbol, using a library for the type.
  - public CSTNode setMeaning(int meaning)
    
    Sets the meaning for this node (and it's root Token). Not valid if the node isEmpty(). Returns this token, for convenience.
  - public void setText(String text)
    
    Not advisable, but if you need to adjust the token's text, this will do it.
  - public int size()
    
    Returns the number of elements in the node (including root).
