Interface AccessLog

All Known Implementing Classes:

AbstractAccessLogValve, AccessLogAdapter, AccessLogValve, ExtendedAccessLogValve, JDBCAccessLogValve, JsonAccessLogValve, StandardEngine.NoopAccessLog

public interface AccessLog

Intended for use by a Valve to indicate that the Valve provides access logging. It is used by the Tomcat internals to identify a Valve that logs access requests so requests that are rejected earlier in the processing chain can still be added to the access log. Implementations of this interface should be robust against the provided Request and Response objects being null, having null attributes or any other 'oddness' that may result from attempting to log a request that was almost certainly rejected because it was mal-formed.

Method Details

log

void log(Request request,
 Response response,
 long time)

Add the request/response to the access log using the specified processing time.

Parameters:

request - Request (associated with the response) to log

response - Response (associated with the request) to log

time - Time taken to process the request/response in milliseconds (use 0 if not known)

setRequestAttributesEnabled

void setRequestAttributesEnabled(boolean requestAttributesEnabled)

Should this valve use request attributes for IP address, hostname, protocol and port used for the request? The attributes used are:

• org.apache.catalina.RemoteAddr
• org.apache.catalina.RemoteHost
• org.apache.catalina.Protocol
• org.apache.catalina.ServerName
• org.apache.catalina.ServerPost

Parameters:

requestAttributesEnabled - true causes the attributes to be used, false causes the original values to be used.

getRequestAttributesEnabled

boolean getRequestAttributesEnabled()

Returns:

true if the attributes will be logged, otherwise false
