Uri Boness commented on SOLR-1644:
----------------------------------
bq. if (rb.store.get(HighlightingComponent.DO_HIGHLIGHTING) == Boolean.TRUE)
This is verbose... too verbose to my taste. I believe a Store interface can
help here which provide access to data by a key and will also provide helper
methods to keep the code clean. (a MapStore can be a simple implementation
which wraps a Map<String, Object> instance):
{code}
public interface Context {
Boolean getBoolean(String key);
boolean getBoolean(String key, boolean defaultValue);
Integer getInt(String key);
int getInt(String key, int defaultValue);
//other methods for all primitive types and dates.
}
{code}
so now you have:
{code}
if (rb.store.getBoolean(HighlightingComponent.DO_HIGHLIGHTING, false))
{code}
which is cleaner and is NPE-safe.
bq. I believe the public API's should have no dependency on components .
I agree. Basically avoid having circular dependencies. You don't want to change
the platform API every time you introduce a new component.

> Many components such as StatsComponent, FacetComponent etc keep flags and
> helper objects in ResponseBuilder. Having to modify the ResponseBuilder for
> such things is a very kludgy solution.
> Let us provide a clean way for components to keep arbitrary objects for the
> duration of a (distributed) search request.
