Examples with DictionaryId com.bakdata.conquery.models.identifiable.ids.specific.DictionaryId used on opensource projects

Example 1 with DictionaryId

use of com.bakdata.conquery.models.identifiable.ids.specific.DictionaryId in project conquery by bakdata.

the class Column method createSharedDictionaryReplacement.

/**
 * Creates an id-replacement mapping for shared dictionaries for an {@link Import}.
 * Because Imports are bound to a {@link com.bakdata.conquery.models.worker.Namespace} but the {@link com.bakdata.conquery.models.preproc.Preprocessed} files are not
 * they contain dummy-{@link NsIdRef}. These References are mapped to actual object with valid ids through this
 * generated mapping.
 * <p>
 * In this method for shared dictionaries, it is ensured, that the shared dictionary exists in the storage and it is
 * created if not.
 *
 * @param dicts                 The mapping of column names in the Import to dictionaries in the Import
 * @param storage               The {@link NamespaceStorage} that backs the dictionaries
 * @param out                   The collection for the generated replacement, that are needed during the deserialization of the next
 *                              part of the {@link com.bakdata.conquery.models.preproc.Preprocessed}-file
 * @param sharedDictionaryLocks A collection of locks used for the synchronized creation of shared dictionaries.
