Parameters
$nodes : array<string|int, mixed>

Array of nodes

Return values
null|array<string|int, Node> —

Array of nodes

beforeTraverse()

Called once before traversal.

public beforeTraverse(array<string|int, mixed> $nodes) : null|array<string|int, Node>

Return value semantics:

  • null: $nodes stays as-is
  • otherwise: $nodes is set to the return value
Parameters
$nodes : array<string|int, mixed>

Array of nodes

Return values

Array of nodes

enterNode()

Called when entering a node.

public enterNode(Node $node) : null|int|Node
Parameters

Node

Return values
null|int|Node —

Replacement node (or special return value)

leaveNode()

Called when leaving a node.

public leaveNode(Node $node) : null|int|Node|array<string|int, Node>

Parameters
$node : Node

Node
