Methods
__construct()
Constructs a name resolution visitor.
public
__construct([ErrorHandler|null $errorHandler = null ][, array<string|int, mixed> $options = [] ]) : mixed
Options:
- preserveOriginalNames (default false): An "originalName" attribute will be added to all name nodes that underwent resolution.
- replaceNodes (default true): Resolved names are replaced in-place. Otherwise, a resolvedName attribute is added. (Names that cannot be statically resolved receive a namespacedName attribute, as usual.)
Parameters
- $errorHandler : ErrorHandler|null = null
-
Error handler
- $options : array<string|int, mixed> = []
-
Options
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)
getNameContext()
Get name resolution context.
public
getNameContext() : NameContext
Return values
NameContext —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)
