= 'instanceof expects an object instance, constant given'
Methods
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()
Validate that the instanceof statement does not receive a scalar value or a non-class constant.
public
enterNode(Node $node) : mixed
Parameters
- $node : Node
Tags
Return values
mixed —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)
