Methods


					
	public

__construct(callable $filterCallback)


					
	public

getFoundNodes(): Node[]

Get found nodes satisfying the filter callback.

Found nodes


					
	public

beforeTraverse(array $nodes): ?array

Called once before traversal.

Return value semantics:

$nodes

Array of nodes

Array of nodes


					
	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

$node

Node

Replacement node (or special return value)
