Enclosing interface:

QueryMap

public static interface QueryMap.Entry

extends java.util.Map.Entry

A QueryMap Entry exposes additional index-related operation that the basic Map Entry does not.

Method Detail

extract

java.lang.Object extract(ValueExtractor extractor)

Extract a value out of the Entry's value. Calling this method is semantically equivalent to extractor.extract(entry.getValue()), but this method may be significantly less expensive. For example, the resultant value may be obtained from a forward index, avoiding a potential object de-serialization.

Parameters:

extractor - a ValueExtractor to apply to the Entry's value

Returns:

the extracted value
