ImportantFunctionOperation
extends FunctionOperation
in package
`FunctionOperation` flavour that must run even when the chain has been rejected by an earlier operation. Used by `MagicFilter::__invert()` (the `~F->…` negation) so a missing attribute upstream still inverts into an accepting `true` rather than collapsing the verdict to `false`.
Mirrors upstream magic_filter.operations.function.ImportantFunctionOperation
(magic_filter/operations/function.py:31-32).

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.
