Create and query iter nodes

Source: R/autogen_node.R
doc_iter.Rd

  • iter_new() instantiates a new iter node.

  • iter_type() checks if the node is a iter node.

  • iter_<child>_get() returns the <child> node of iter.

  • iter_<child>_set() sets the new <child> and deletes the old <child>.

  • iter_<child>_rep() sets the new <child> and returns the old <child>.
