Class StringFieldLoadingStrategy

java.lang.Object
org.hibernate.search.query.fieldcache.StringFieldLoadingStrategy
All Implemented Interfaces:
FieldLoadingStrategy
public final class StringFieldLoadingStrategy 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. This particular implementation doesn't do any conversion.

    • collect

      public String collect(int relativeDocId)

      collect in interface FieldLoadingStrategy
      Parameters:
      relativeDocId - the doc id relative to the current reader
      Returns:
