Protected Member Functions

ComparableMin ()

Default constructor (necessary for the PortableObject interface).

ComparableMin (ValueExtractor::View vExtractor)

Construct a ComparableMin aggregator.

virtual void process (Object::View v, bool fFinal)

Incorporate one aggregatable value into the result.

If the fFinal parameter is true, the given object is a partial result (returned by an individual parallel aggregator) that should be incorporated into the final result; otherwise, the object is a value extracted from an coherence::util::InvocableMap::Entry.

Parameters:

	vO	the value to incorporate into the aggregated result
	fFinal	true to indicate that the given object is a partial result returned by a parallel aggregator
