Interface MoveCheckable

All Known Implementing Classes:
EmptyTerminalNode
public interface MoveCheckable
The move checkable interface provides a method for checking if the implementing node replaces a given node. This is helpful for the dynamic parse tree walker in determining if the current node is was looking at has moved or was replaced by an empty terminal node. All nodes that are not terminal nodes with tokens should implement this interface in the parse tree.

    Description
    static boolean
    replaces(org.antlr.v4.runtime.tree.ParseTree oldNode, org.antlr.v4.runtime.tree.ParseTree newNode)
    Checks if any given parse tree node replaces another.
    boolean
    replacesNode(org.antlr.v4.runtime.tree.ParseTree node)
    Checks if the implementing object was inserted into the tree to replace the given node.

    • replacesNode

      boolean replacesNode(org.antlr.v4.runtime.tree.ParseTree node)
      Checks if the implementing object was inserted into the tree to replace the given node. This is used to check if an empty terminal node replaced this node in the parse tree.
      Parameters:
      node - The node to check for having been replaced by this node
      Returns:
      true if this node replaced the given node

    • replaces

      static boolean replaces(org.antlr.v4.runtime.tree.ParseTree oldNode, org.antlr.v4.runtime.tree.ParseTree newNode)
      Checks if any given parse tree node replaces another. This also deals with some nodes being regular terminal nodes and maybe not implementing this interface. Otherwise it does the same thing as replacesNode(ParseTree).
      Parameters:
      oldNode - The node having maybe been replaced
      newNode - The node that could be the replacement
      Returns:
      true if the new node replaced the old node
