RCombinationOperation
extends BaseOperation
in package
Reverse-binary combinator: the running value is on the RIGHT and a fixed literal (or nested `MagicFilter`) is on the LEFT. Powers the `__rxxx__` family of upstream operators — for example `'pong' + F.text` produces an `RCombinationOperation(left='pong', combinator=add)` whose `resolve(value)` returns `'pong' . $value`.
Mirrors upstream magic_filter.operations.combination.RCombinationOperation
(magic_filter/operations/combination.py:25-37).

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.
