Class PhpParser\NodeVisitor\ParentConnectingVisitor

`final`
`extends`	`NodeVisitorAbstract`

Visitor that connects a child node to its parent node.

With $weakReferences=false on the child node, the parent node can be accessed through $node->getAttribute('parent').

With $weakReferences=true the attribute name is "weak_parent" instead.

otherwise: $nodes is set to the return value

Parameters

$nodes

Array of nodes

Returns

Array of nodes

Overrides

PhpParser\NodeVisitorAbstract::beforeTraverse()


					
	public

enterNode(Node $node)

Called when entering a node.

Return value semantics:

null => $node stays as-is
array (of Nodes) => The return value is merged into the parent array (at the position of the $node)
NodeVisitor::REMOVE_NODE => $node is removed from the parent array
NodeVisitor::REPLACE_WITH_NULL => $node is replaced with null
NodeVisitor::DONT_TRAVERSE_CHILDREN => Children of $node are not traversed. $node stays as-is
NodeVisitor::DONT_TRAVERSE_CURRENT_AND_CHILDREN => Further visitors for the current node are skipped, and its children are not traversed. $node stays as-is.
NodeVisitor::STOP_TRAVERSAL => Traversal is aborted. $node stays as-is
otherwise => $node is set to the return value

Parameters

$node

Node

Returns

Replacement node (or special return value)
