Subject [jira] Commented: (SOLR-969) Context#FULL_DUMP, DELTA_DUMP, FIND_DELTA as an enum
Date Wed, 21 Jan 2009 04:33:59 GMT

    [ https://issues.apache.org/jira/browse/SOLR-969?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12665699#action_12665699

Noble Paul commented on SOLR-969:
---------------------------------

All the Objects can be consumed directly from JS , just the way we use it in java .
example
{code}
<dataConfig>
        <script><![CDATA[
                function f1(row, context)        {
                    var cmd =  context.getVariableResolver().replaceTokens('${dataimporter.request.command}');
                    if(cmd == 'full-import')
                        row.put('message', 'The command is full-import');
                    return row;
                }
        ]]></script>
        <document>
                <entity name="e" pk="id" transformer="script:f1" query="select * from X">
                ....
                </entity>
        </document>
</dataConfig>
{code}

Currently only a Transformer can be written in JS and that is the most common extension point.


It is hard to write a DataSource/EntityProcessor in JS . I'm interested in having an Entityprocessor
written in non-java. but there has not been much interest in it.

 an Eventlistener can be easily written in JS (but not yet implemented)
