Plugin development : doc.get(key) types?

Yann_Barraud · September 13, 2013, 4:41am

Hi,

I'm building a new plugin, but did not find a simple way to parse a
matching doc.

I wish to get doc.get(key) values wether in their original type
(ScriptDocValues.xxx) or as String. Am I obliged to iterate
throughScriptDocValues types ?

Thanks.

Regards,
Yann

Hi,
For anyone interested, you'll find what I did here :

github.com

YannBrrd/elasticsearch-entity-resolution/blob/0.2/src/main/java/org/yaba/entity/script/EntityResolutionScript.java#L410


      
                      .floatValue();

          }

          

          /**

           * . Reads field value & returns it as String

           * 

           * @param field

           *            the object to cast

           * @return String object String value

           */

          private static String getFieldValue(final Object field) {

              String result = "";

          

              if (field instanceof ScriptDocValues.Strings)

                  result = ((ScriptDocValues.Strings) field).getValue();

              if (field instanceof ScriptDocValues.Doubles)

                  result =

                          Double.toString(((ScriptDocValues.Doubles) field)

                                  .getValue());

              if (field instanceof ScriptDocValues.Longs)

                  result = Long.toString(((ScriptDocValues.Longs) field).getValue());

If you have any suggestion about doing better, I'll be glad to know.

Regards,

Yann
