Class FloatFieldLoadingStrategy

java.lang.Object

org.hibernate.search.query.fieldcache.impl.FloatFieldLoadingStrategy

All Implemented Interfaces:

FieldLoadingStrategy

public final class FloatFieldLoadingStrategy
extends Object
implements FieldLoadingStrategy

We need a collection of similar implementations, one per each FieldCache.DEFAULT.accessmethod to be able to deal with arrays of primitive values without autoboxing all of them.
