Class AwsHttpServletResponse

java.lang.Object

com.amazonaws.serverless.proxy.internal.servlet.AwsHttpServletResponse

All Implemented Interfaces:

javax.servlet.http.HttpServletResponse, javax.servlet.ServletResponse

public class AwsHttpServletResponse
extends java.lang.Object
implements javax.servlet.http.HttpServletResponse

Basic implementation of the HttpServletResponse object. This is used by the AwsProxyHttpServletResponseWriter to generate an AwsProxyResponse object. We have an additional getAwsResponseHeaders() method that returns a Map<String, String> that can be used for our proxy response object.
