• public Token(int type, String text, int startLine, int startColumn)

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 nodes as the second and third element, respectively.

• 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.

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

• public Token dup()

• public CSTNode get(int index)

• 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 token. Equivalent to getRootText() when called directly.

• public int getStartColumn()

• public int getStartLine()

  Creates a token that represents a decimal number.

• 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.

  Creates a token with the specified meaning.

• public CSTNode setMeaning(int meaning)

• public void setText(String text)

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

• public int size()

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