    • getReturnValue

      public AstNode getReturnValue()
      Returns return value, null if return value is void
    • setReturnValue

      public void setReturnValue(AstNode returnValue)
      Sets return value expression, and sets its parent to this node. Can be null.
    • toSource

      public String toSource(int depth)
      Description copied from class: AstNode
      Emits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.

      Note: if the parser was in error-recovery mode, some AST nodes may have null children that are expected to be non-null when no errors are present. In this situation, the behavior of the toSource method is undefined: toSource implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

      Specified by:
      toSource in class AstNode
      Parameters:
      depth - the current recursion depth, typically beginning at 0 when called on the root node.
    • visit

      public void visit(NodeVisitor v)
      Visits this node, then the return value if specified.
      Specified by:
      visit in class AstNode
      Parameters:
      v - the object to call with this node and its children
