#include <coherence/util/aggregator/ComparableMax.hpp>
Inherits AbstractComparableAggregator.
This aggregator is most commonly used with objects that implement Comparable
such as String
; a
Comparator
can also be supplied to perform the comparisons.

Protected Member Functions | |||||||
ComparableMax () | |||||||
Default constructor (necessary for the PortableObject interface). | |||||||
ComparableMax (ValueExtractor::View vExtractor, Comparator::View vComparator=NULL) | |||||||
Construct a ComparableMax aggregator. | |||||||
ComparableMax (String::View vsMethod, Comparator::View vComparator=NULL) | |||||||
Construct a ComparableMax that will aggregate values extracted from a set of InvocableMap::Entry objects. | |||||||
virtual void | process (Object::View v, bool fFinal) | ||||||
Incorporate one aggregatable value into the result.
If the
|
ComparableMax | ( | ValueExtractor::View | vExtractor, | |
Comparator::View | vComparator = NULL | |||
) | [protected] |
Construct a ComparableMax aggregator.
vExtractor | the extractor that provides an object to be compared | |
vComparator | the comparator used to compare the extracted object, if NULL then the extracted object must implement Comparable |
ComparableMax | ( | String::View | vsMethod, | |
Comparator::View | vComparator = NULL | |||
) | [protected] |
Construct a ComparableMax that will aggregate values extracted from a set of InvocableMap::Entry objects.
vsMethod | the name of the method that could be invoked via reflection and that returns values to aggregate; this parameter can also be a dot-delimited sequence of method names which would result in an aggregator based on the ChainedExtractor that is based on an array of corresponding ReflectionExtractor objects | |
vComparator | the comparator used to compare the extracted object, if NULL then the extracted object must implement Comparable |
