the class ImportsAwareReferenceProposalCreator method lookupCrossReference.

 *            usually this will be an instance of

 * @param filter
 *            by default an instance of {@link N4JSCandidateFilter} will be provided here.

 * First step in comparing API and implementation projects. This method will collect all API projects, the types

 * The second step of comparison is to compare an individual type/member to a corresponding type/member of a
 * particular implementation via method {@link #compareApiImpl(ProjectComparisonEntry, int)}.
 * <p>
 * Usually, this second step is performed lazily when method <code>#compareApiImpl()</code> is invoked; however, by
 * setting <code>fullCompare</code> to <code>true</code>, this is performed up-front here causing all results to be
 * stored in a cache in the entries, and then subsequent calls to <code>#compareApiImpl()</code> will just read from
 * that cache.
 * <p>
 * Returns <code>null</code> in case of error and adds human-readable error messages to the given list.
