    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.

Since:
  Coherence 3.2

Methods inherited from interface java.util.Map.Entry
`equals, getKey, getValue, hashCode, setValue`

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
