Method Details

containsAnyAlias

public static boolean containsAnyAlias(@Nullable
 Filters filters,
 @Nullable
 Sort sort,
 String... aliases)

Check if an alias is mentioned in a set of Filter.

This should be used to eliminate parts of an HQL query that are not mentioned in the filters.

Returns:

true if any provided alias is mentioned anywhere in the set of filters

unnestSubquery

public static Filter unnestSubquery(Filter f)

Unnest a filter from a subquery.

A subquery carrying a conjunction unnests to its FIRST conjunct. The only caller validates the right-hand side of a collection operator, and the quantified-conjunction syntax puts the collection operator on the first predicate; there is no single filter to return otherwise.
