Method Details

disjoint

public static List<PojoMassIndexingIndexedTypeGroup<?>> disjoint(PojoMassIndexingMappingContext mappingContext,
 PojoMassIndexingTypeContextProvider typeContextProvider,
 Set<? extends PojoMassIndexingIndexedTypeContext<?>> indexedTypeContexts,
 PojoMassLoadingContext loadingContext)

Group indexed types by their closest common supertype, ensuring returned groups are disjoint (i.e.no two groups have any common indexed subtype among those provided) .

This is necessary to avoid duplicate indexing.

For example, without this, we could end up reindexing type B in one thread, and its superclass A (which will include all instances of B) in another.

Parameters:

mappingContext - The mapping context.

typeContextProvider - A provider of type contexts, used for some reflection operations.

indexedTypeContexts - A set of indexed types to group together.

loadingContext - Mapper-specific loading context.

Returns:

One or more type groups that are guaranteed to be disjoint.
