public Interface ReaderInterceptor

Interface for message body reader interceptors that wrap around calls to jakarta.ws.rs.ext.MessageBodyReader#readFrom.

Providers implementing ReaderInterceptor contract must be either programmatically registered in a JAX-RS runtime or must be annotated with @Provider annotation to be automatically discovered by the JAX-RS runtime during a provider scanning phase. Message body interceptor instances may also be discovered and bound dynamically to particular resource methods.
