Detailed Description

A reference to a node in an existing yaml tree, offering a more convenient API than the index-based API used in the tree.

Unlike its imutable ConstNodeRef peer, a NodeRef can be used to mutate the tree, both by writing to existing nodes and by creating new nodes to subsequently write to. Semantically, a NodeRef object can be in one of three states:

invalid  := not pointing at anything
readable := points at an existing tree/node
seed     := points at an existing tree, and the node
            may come to exist, if we write to it.

So both readable and seed are states where the node is also valid.

Tree t = parse_in_arena("{a: b}");
NodeRef invalid; // not pointing at anything.
NodeRef readable = t["a"]; // also valid, because "a" exists
NodeRef seed = t["none"]; // also valid, but is seed because "none" is not in the map

When the object is in seed state, using it to read from the tree is UB. The seed node can be used to write to the tree, provided that its create() method is called prior to writing, which happens in most modifying methods in NodeRef.

It is the owners's responsibility to verify that an existing node is readable before subsequently using it to read from the tree.

Warning

The lifetime of the tree must be larger than that of this object. It is up to the user to ensure that this happens.

operator[]() [1/4]

auto c4::yml::detail::RoNodeMethods< NodeRef , ConstNodeRef >::operator[] ( csubstr  key ) -> NodeRef

inlineinherited

Find child by key; complexity is O(num_children).

Returns the requested node, or an object in seed state if no such child is found (see NodeRef for an explanation of what is seed state). When the object is in seed state, using it to read from the tree is UB. The seed node can be used to write to the tree provided that its create() method is called prior to writing, which happens in most modifying methods in NodeRef. It is the caller's responsibility to verify that the returned node is readable before subsequently using it to read from the tree.

Warning

the calling object must be readable. This precondition is asserted. The assertion is performed only if RYML_USE_ASSERT is set to true. As with the non-const overload, it is UB to call this method if the node is not readable.

auto c4::yml::detail::RoNodeMethods< NodeRef , ConstNodeRef >::at ( csubstr  key ) -> NodeRef

inlineinherited

Find child by key; complexity is O(num_children).

Returns the requested node, or an object in seed state if no such child is found (see NodeRef for an explanation of what is seed state). When the object is in seed state, using it to read from the tree is UB. The seed node can be subsequently used to write to the tree provided that its create() method is called prior to writing, which happens inside most mutating methods in NodeRef. It is the caller's responsibility to verify that the returned node is readable before subsequently using it to read from the tree.

Warning

This method will call the error callback (regardless of build type or of the value of RYML_USE_ASSERT) whenever any of the following preconditions is violated: a) the object is valid (points at a tree and a node), b) the calling object must be readable (must not be in seed state), c) the calling object must be pointing at a MAP node. The preconditions are similar to the non-const operator[](csubstr), but instead of using assertions, this function directly checks those conditions and calls the error callback if any of the checks fail.

Note

since it is valid behavior for the returned node to be in seed state, the error callback is not invoked when this happens.
