> In an effort to make SOLR-139 (the "modify" command) more manageable, i
> extracted out a large chunk. This patch adds a general SolrDocument
> interface and includes a concrete implementation (SimpleSolrDoc)
> SOLR-139 needs some way to transport document values independent of the
> lucene Document. This is required for the INCREMENT command and useful for
> modifying documents. SolrDocument is also generally useful for SOLR-20
> - - - - - -
> The one (potentially) controversial part is that I added a function to
> FieldType:
> public Object toExternalValue(Fieldable f);
> This asks each field type to convert its Fieldable into its real type, for
> example IntField.java has:
> public Integer toExternalValue(Fieldable f) {
> return Integer.valueOf( toExternal(f) );
> }
> By default, it returns a string value. If this addition is too much, there
> are other (less clean) ways to handle the INCREMENT command. My real
> motivation for this addition is that it makes it possible to implement an
> embeddable SOLR-20 client that does not need an HTTP connection.
> - - - -
> The SimpleSolrDoc implementation was written for SOLR-20. It needs to play
> nice with EL, so it implements a few extra map function that may not seem
> necessary:
> ${doc.values['name']]} gets a collection
> ${doc.valueMap['name']]} gets a single value for the field
> - - - -
> The tests cover all "toExternalValue" changes in schema.*
> SimpleSolrDoc and DocumentBuilder have 100% test coverage.
