Inherits AbstractInteger64Aggregator.

List of all members.

Detailed Description

Calculates a maximum of numeric values extracted from a set of entries in a Map.

All the extracted Number objects will be treated as int64_t values.

Protected Member Functions

 Integer64Max ()
 Default constructor (necessary for the PortableObject interface).
 Integer64Max (ValueExtractor::View vExtractor)
 Construct a Integer64Max aggregator.
virtual void init (bool fFinal)
 Initialize the aggregation result.

fFinal true is passed if the aggregation process that is being initialized must produce a final aggregation result; this will only be false if a parallel approach is being used and the initial (partial) aggregation process is being initialized

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.

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

Constructor & Destructor Documentation
