      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 ParseTree 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 Tree

    • setParent

      public void setParent(RuleContext parent)
      Description copied from interface: ParseTree
      Set the parent for this node. This is not backward compatible as it changes the interface but no one was able to create custom nodes anyway so I'm adding as it improves internal code quality. One could argue for a restructuring of the class/interface hierarchy so that setParent, addChild are moved up to Tree but that's a major change. So I'll do the minimal change, which is to add this method.
      Specified by:
      setParent in interface ParseTree

    • 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
