Member Function Documentation

virtual Object::Holder extract

(

ValueExtractor::View

vExtractor

)

const [pure virtual]

Extract a value out of the Entry's value.

Calling this method is semantically equivalent to vExtractor->extract(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:

vExtractor

a ValueExtractor to apply to the Entry's value

Returns:

the extracted value
