Examples of javax.ws.rs.core.StreamingOutput

javax.ws.rs.core.StreamingOutput
A type that may be used as a resource method return value or as the entity in a {@link Response} when the application wishes to stream the output.This is a lightweight alternative to a {@link javax.ws.rs.ext.MessageBodyWriter}. @see javax.ws.rs.ext.MessageBodyWriter @see javax.ws.rs.core.Response
