    • Method Detail

      • 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
      • 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
      • getPayload

        public Token getPayload()
        Description copied from interface: Tree
        This method returns whatever object represents the data at this note. 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.

        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
      • 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
      • 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
