Interface InputValidator

All Known Implementing Classes:
PiiInputValidator
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface InputValidator
Validates one string-valued action parameter before dispatch.

Implementations declared through InputGuardrail.validators() must expose a public no-argument constructor and must not retain the inspected value. Returning false delegates disposition to the guardrail's configured failure action.

      Parameters:
      input - string parameter value, never null
      Returns:
      true when the value may continue through the action pipeline

    • validatesParameterNames

      default boolean validatesParameterNames()
      Returns whether this validator also protects parameter names before value validation. Domain validators normally leave this disabled; security classifiers that treat keys as user-visible prompt data may opt in.
      Returns:
