Interface HstResponseState

public interface HstResponseState

Temporarily holds the current state of a HST response. Basically the response of each HstComponent is buffered and stored in a HstResponseState implementation. At the final stage, the HstComponent container will flush every buffered content by using this HstResponseState implementation. Therefore, this interface has all the similar methods which can be found in HttpServletResponse to keep the contents buffered.
