      public TerminalNodeImpl(Token symbol)

  • Method Details

    • getChild

      public ParseTree getChild(int i)
      Description copied from interface: Tree
      If there are children, get the ith value indexed from 0.
      Specified by:
      getChild in interface ParseTree
      Specified by:
      getChild in interface Tree

    • getSymbol

      public Token getSymbol()
      Specified by:
      getSymbol in interface TerminalNode

    • getParent

      public RuleNode getParent()
      Description copied from interface: Tree
      The parent of this node. If the return value is null, then this node is the root of the tree.
      Specified by:
      getParent in interface ParseTree
      Specified by:
      getParent in interface TerminalNode
      Specified by:
      getParent in interface Tree

    • setParent

      public void setParent(RuleContext parent)

    • getPayload

      public Token getPayload()
      Description copied from interface: Tree
      This method returns whatever object represents the data at this node. For example, for parse trees, the payload can be a Token representing a leaf node or a RuleContext object representing a rule invocation. For abstract syntax trees (ASTs), this is a Token object.
      Specified by:
      getPayload in interface Tree

    • getSourceInterval

      public Interval getSourceInterval()
      Description copied from interface: SyntaxTree
      Return an Interval indicating the index in the TokenStream of the first and last token associated with this subtree. If this node is a leaf, then the interval represents a single token and has interval i..i for token index i.

      An interval of i..i-1 indicates an empty interval at position i in the input stream, where 0 <= i <= the size of the input token stream. Currently, the code base can only have i=0..n-1 but in concept one could have an empty interval after EOF.

      If source interval is unknown, this returns Interval.INVALID.

      As a weird special case, the source interval for rules matched after EOF is unspecified.

      Specified by:
      getSourceInterval in interface SyntaxTree

    • getChildCount

      public int getChildCount()
      Description copied from interface: Tree
      How many children are there? If there is none, then this node represents a leaf node.
      Specified by:
      getChildCount in interface Tree

    • accept

      public <T> T accept(ParseTreeVisitor<? extends T> visitor)
      Description copied from interface: ParseTree
      The ParseTreeVisitor needs a double dispatch method.
      Specified by:
      accept in interface ParseTree

    • getText

      public String getText()
      Description copied from interface: ParseTree
      Return the combined text of all leaf nodes. Does not get any off-channel tokens (if any) so won't return whitespace and comments if they are sent to parser on hidden channel.
      Specified by:
      getText in interface ParseTree

    • toStringTree

      public String toStringTree(Parser parser)
      Description copied from interface: ParseTree
      Specialize toStringTree so that it can print out more information based upon the parser.
      Specified by:
      toStringTree in interface ParseTree

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • toStringTree

      public String toStringTree()
      Description copied from interface: Tree
      Print out a whole tree, not just a node, in LISP format (root child1 .. childN). Print just a node if this is a leaf.
      Specified by:
      toStringTree in interface Tree
