GetAttributeOperation
extends BaseOperation
in package
Read a named attribute from the running value: `F->message->text` resolves to `$value->text` (object) or `$value['text']` (array/ArrayAccess).
Mirrors upstream magic_filter.operations.getattr.GetAttributeOperation
(magic_filter/operations/getattr.py). Python's single getattr() covers
both attribute and item-like lookups via __getattr__; PHP splits them
but MagicFilter::__get always dispatches here, so we honour the same
fallback for arrays / ArrayAccess to keep AttrDict-style call sites
working.
On lookup failure we raise RejectOperations so the resolver short-
circuits the rest of the chain (and an upstream __invert__ / OR can
still rescue the verdict via the important flag).

Methods
- __construct() : mixed
- important() : bool
- `true` for operations that must always evaluate even when an earlier step in the chain raised `RejectOperations`. The canonical example is `~F->message->text` (`ImportantFunctionOperation` wrapping logical NOT): if `text` is missing we want the negation to still flip the `null` result to `true` rather than collapse to `false`.
- resolve() : mixed
- Evaluate this operation.

important()
`true` for operations that must always evaluate even when an earlier step in the chain raised `RejectOperations`. The canonical example is `~F->message->text` (`ImportantFunctionOperation` wrapping logical NOT): if `text` is missing we want the negation to still flip the `null` result to `true` rather than collapse to `false`.

Subclasses opt in by extending ImportantBaseOperation or by
overriding this method directly.
Return values
boolresolve()
Evaluate this operation.
public
resolve(mixed $value, mixed $initialValue) : mixed
Parameters
- $value : mixed
-
The current running value (output of the previous operation, or the original subject for the first step).
- $initialValue : mixed
-
The original subject passed to
MagicFilter::resolve. Used by combinator / comparator operations that need to resolve a nestedMagicFilteragainst the root rather than the current intermediate value.
