package jakarta.ws.rs.ext;

Interface for message body writer interceptors that wrap around calls to MessageBodyWriter.writeTo. 
 Providers implementing WriterInterceptor 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.

Interceptor method wrapping calls to MessageBodyWriter.writeTo method. The parameters of the wrapped method called are available from context.

Params:
context – invocation context.
Throws:
IOException – if an IO error arises or is thrown by the wrapped MessageBodyWriter.writeTo method.
WebApplicationException – thrown by the wrapped MessageBodyWriter.writeTo method./**
