Subject [jira] Created: (HTTPCORE-65) Allow for explicit null in HttpContext and HttpParams
Date Sat, 07 Apr 2007 11:17:32 GMT
Allow for explicit null in HttpContext and HttpParams
-----------------------------------------------------

                 Key: HTTPCORE-65
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-65
             Project: HttpComponents Core
          Issue Type: Improvement
          Components: HttpCore
    Affects Versions: 4.0-alpha4
            Reporter: Roland Weber
            Priority: Minor


Both HttpContext and HttpParams support hierarchies. The current implementations ([Sync]HttpExecutionContext,
BasicHttpParams) do allow for overriding a parent/default value with another value, but they
do not allow for overriding with null. Implementation alternatives:
- lookup the map entry instead of the value, do not fall back to parent/default if an entry
is there with a null value
- use a dedicated constant to represent an explicit null value

cheers,
  Roland
