    - #### hasSideEffects

          public boolean hasSideEffects()

      Overrides:
        `hasSideEffects` in class `AstNode`

    - #### toSource

          public java.lang.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 test-expression, the true-expression, and the false-expression.
      Specified by:
        `visit` in class `AstNode`
      Parameters:
        `v` - the object to call with this node and its children
