Problem/Motivation

In #2976334: Allow Custom blocks to be set as non-reusable adding access restriction based on where it was used. we had to put logic in to check if there was a condition 'reusable' so we didn't add a condition if there already one was one.

@wim leers and @larowlan both suggested it would be nice if there was API around this.

Proposed resolution

Add a method hasCondition() to \Drupal\Core\Database\Query\ConditionInterface
or find a better place this API.

Remaining tasks

User interface changes

API changes

Data model changes

If you want to checks if a condition is empty you can also test on empty($condition->__toString()).

Would calling the method isEmptyCondition() be a better name for what you want?

Imho this stems from the fact that the basic paradigm of this class is being a query builder, not a declarative abstraction.
That said, having this makes sense.

I'd prefer an API like this:

// This also has #parents.
$conditionyByField = $query->conditionsByField();
if (isset($conditionyByField['reusable'])) {...}
