Apply spans as a method inherited in all filter services

[LucasGois1]

I'm implementing a lot of filters based on implementations of regex filters, and I have an usecase where i can raise exception if detected PII in the string, or you can select to accept the anonymization, but, this services doesn't implement the apply method because don't implement the FilterService, there is an easy way to apply the spans without building another service PhileasFilterService? Or this is the way ?

Hi @LucasGois1, I don't think there is an easier way right now. An apply() method outside of FilterService might be a good idea.

And just some background for others that might come along and find this issue, the purpose of the apply() method in FilterService is to let you redact a list of Spans that have been previously identified. For example, you redact some text but later decide you actually don't want all of those redactions, you can modify the list of Spans, send it to apply() and just get back those redacted spans. (Right now apply() only works on text and not PDFs.)
