Package com.tnsai.quality.redaction

Class CompositeRedactor

java.lang.Object

com.tnsai.quality.redaction.CompositeRedactor

All Implemented Interfaces:

Redactor

public final class CompositeRedactor
extends Object
implements Redactor

Pipes input through a chain of Redactors in order (issue #80). Each redactor's output text feeds the next, and findings concatenate across the chain.

Composition lets operators stack a fast-path PatternRedactor (catches credentials + structured PII) with a heavier LLM-classifier or Presidio bridge (catches names / addresses / health information that don't pattern-match cleanly) without either implementation knowing about the other.

Order matters: the first redactor's placeholders ([REDACTED:...]) pass through every later redactor unchanged, so a downstream LLM classifier doesn't get to "explain" what was already scrubbed.

Since:

0.5.0 (issue #80)

scrubString

public RedactionResult scrubString(String input,
 RedactionContext ctx)

Description copied from interface: Redactor

Scrub sensitive patterns out of input, returning the redacted text + every match.

Specified by:

scrubString in interface Redactor

Parameters:

input - plaintext to scan; never null. "" is acceptable and returns an unchanged result.

ctx - per-call context (sink, tenant policy)

Returns:

redacted text + findings; never null

maybeContainsSensitive

public boolean maybeContainsSensitive(String input)

Description copied from interface: Redactor

Cheap pre-check: returns true when input might contain something worth scanning. Lets the framework short-circuit the regex loop on guaranteed-clean strings (UUIDs, numeric IDs, fixed-vocabulary enums). Default true because the safe fallback is "always scan"; override when you can do better.

Specified by:

maybeContainsSensitive in interface Redactor
