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

Field Detail

### EOF

    public static final Token EOF

### NULL

    public static final Token NULL

Constructor Detail

### Token

    public Token(int type, java.lang.String text, int startLine, int startColumn)

Method Detail

### asReduction

    public Reduction asReduction()

  Creates a `Reduction` from this token. Returns self if the node is already a `Reduction`.

### asReduction

    public Reduction asReduction(CSTNode second)

  Creates a `Reduction` from this token, adding the supplied nodes as the second and third element, respectively.

### asReduction

    public Reduction asReduction(CSTNode second, CSTNode third)

  Creates a `Reduction` from this token, adding the supplied nodes as the second, third, and fourth element, respectively.

### asReduction

    public Reduction asReduction(CSTNode second, CSTNode third, CSTNode fourth)

### dup

    public Token dup()

### get

    public CSTNode get(int index)

### getMeaning

    public int getMeaning()

  Returns the meaning of this node. If the node isEmpty(), returns the type of Token.NULL.

### getRoot

    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()`.

### getRootText

    public java.lang.String getRootText()

  Returns the text of the token. Equivalent to `getRootText()` when called directly.

### getStartColumn

    public int getStartColumn()

### getStartLine

    public int getStartLine()

  Returns the starting column of the node. Returns -1 if not known.

### getText

    public java.lang.String getText()

  Not advisable, but if you need to adjust the token's text, this will do it.

### getType

    public int getType()

### newDecimal

    public static Token newDecimal(java.lang.String text, int startLine, int startColumn)

  Creates a token that represents a symbol, using a library for the text.

### newIdentifier

    public static Token newIdentifier(java.lang.String text, int startLine, int startColumn)

  Creates a token that represents an integer.

### newInteger

    public static Token newInteger(java.lang.String text, int startLine, int startColumn)

  Creates a token that represents a decimal number.

### newKeyword

    public static Token newKeyword(java.lang.String text, int startLine, int startColumn)

  Creates a token that represents a keyword. Returns null if the specified text isn't a keyword.

### newPlaceholder

    public static Token newPlaceholder(int type)

### newString

    public static Token newString(java.lang.String text, int startLine, int startColumn)

  Creates a token that represents an identifier.

### newSymbol

    public static Token newSymbol(int type, int startLine, int startColumn)

  Creates a token that represents a symbol, using a library for the type.

### newSymbol

    public static Token newSymbol(java.lang.String type, int startLine, int startColumn)

  Creates a token with the specified meaning.

### setMeaning

    public CSTNode setMeaning(int meaning)

### setText

    public void setText(java.lang.String text)

  Returns the starting line of the node. Returns -1 if not known.

### size

    public int size()

  Returns the number of elements in the node (including root).
