Example 31 with ConfigurableCompletionProposal

use of org.eclipse.xtext.ui.editor.contentassist.ConfigurableCompletionProposal in project n4js by eclipse.

the class ImportsAwareReferenceProposalCreator method lookupCrossReference.

/**
 * Retrieves possible reference targets from scope, including erroneous solutions (e.g., not visible targets). This
 * list is further filtered here. This is a general pattern: Do not change or modify scoping for special content
 * assist requirements, instead filter here.
 *
 * @param proposalFactory
 *            usually this will be an instance of
 *            {@link AbstractJavaBasedContentProposalProvider.DefaultProposalCreator DefaultProposalCreator}.
 * @param filter
 *            by default an instance of {@link N4JSCandidateFilter} will be provided here.
