[jira] [Commented] (SOLR-7915) Provide pluggable Velocity context tool facility

["Noble Paul (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-7915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14725215#comment-14725215 ] 

Noble Paul commented on SOLR-7915:
----------------------------------

ideally the design could be as follows

VRW can implement ResourceLoaderAware . It should have the appropriate {{ResourceLoader}} depending on whether it had {{runtimeLib=true}} specified or not it would get the right ResourceLoader

use the resourceLoader on core.createInstance() to instantiate your tool

> Currently the "tools" placed in the VelocityResponseWriter's context are hard-coded.  It can be very handy to be able to plug in 3rd party or custom tools (just any ol' Java object a "tool" can be).
