Examples of javax.ws.rs.ext.MessageBodyReader.readFrom()

javax.ws.rs.ext.MessageBodyReader.readFrom()
Read a type from the {@link InputStream}. @param type the type that is to be read from the entity stream. @param genericType the type of instance to be produced. E.g. if themessage body is to be converted into a method parameter, this will be the formal type of the method parameter as returned by {@code Method.getGenericParameterTypes}. @param annotations an array of the annotations on the declaration of theartifact that will be initialized with the produced instance. E.g. if the message body is to be converted into a method parameter, this will be the annotations on that parameter returned by {@code Method.getParameterAnnotations}. @param mediaType the media type of the HTTP entity. @param httpHeaders the read-only HTTP headers associated with HTTP entity. @param entityStream the {@link InputStream} of the HTTP entity. Thecaller is responsible for ensuring that the input stream ends when the entity has been consumed. The implementation should not close the input stream. @return the type that was read from the stream. @throws java.io.IOException if an IO error arises @throws javax.ws.rs.WebApplicationException if a specific HTTP error response needs to be produced. Only effective if thrown prior to the response being committed.
