Class HanaHints

java.lang.Object

de.hybris.platform.jalo.flexiblesearch.hints.impl.HanaHints

All Implemented Interfaces:

Hint, QueryHint

public final class HanaHints
extends java.lang.Object
implements QueryHint

Allows to build HANA optimizer/query hints. Keep in mind that you should use just one QueryHint for FlexibleSearchQuery. That means adding more than one will lead to query errors. You can combine more than one optimiser hints by using create(String...) (String...)} as follows:

 QueryHint hint = HanaHints.create("HINT_ONE", "HINT_TWO");
 

and then pass it to the FlexibleSearchQuery object using FlexibleSearchQuery.addHints(Hint...) method. All provided hints will be compiled into one HANA hint directive and added to the end of the query:

     WITH HINT(HINT_ONE,HINT_TWO)
 

If you need to add more hints to existing object, for instance iterating over some list of objects, you can use method add(String).
