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 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 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(String text, int startLine, int startColumn)
Creates a token that represents a symbol, using a library for the text.

newIdentifier

public static Token newIdentifier(String text, int startLine, int startColumn)
Creates a token that represents an integer.

newInteger

public static Token newInteger(String text, int startLine, int startColumn)
Creates a token that represents a decimal number.

newKeyword

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.

newPlaceholder

public static Token newPlaceholder(int type)

newString

public static Token newString(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(String type, int startLine, int startColumn)
Creates a token with the specified meaning.

setMeaning

public CSTNode setMeaning(int meaning)

setText

public void setText(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).
