Properties

Methods

__construct()

public __construct(bool $shortCircuitTraversal) : mixed
Parameters
$shortCircuitTraversal : bool
Return values
mixed —

afterTraverse()

Called once after traversal.

public afterTraverse(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
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
null|array<string|int, Node> —

Array of nodes

enterNode()

Called when entering a node.

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

Return value semantics:

  • null => $node stays as-is
  • NodeTraverser::DONT_TRAVERSE_CHILDREN => Children of $node are not traversed. $node stays as-is
  • NodeTraverser::STOP_TRAVERSAL => Traversal is aborted. $node stays as-is
  • otherwise => $node is set to the return value
Parameters
$node : Node

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>

Return value semantics:

  • null => $node stays as-is
  • NodeTraverser::REMOVE_NODE => $node is removed from the parent array
  • NodeTraverser::STOP_TRAVERSAL => Traversal is aborted. $node stays as-is
  • array (of Nodes) => The return value is merged into the parent array (at the position of the $node)
  • otherwise => $node is set to the return value
Parameters
$node : Node

Node

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

Replacement node (or special return value)

cyclomaticComplexity()

private cyclomaticComplexity(array<string|int, Stmt> $statements) : int
Parameters
$statements : array<string|int, Stmt>
Return values
int —
