Inherits AbstractFloat64Aggregator.

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 float64_t values.

Protected Member Functions

Float64Max ()

Default constructor (necessary for the PortableObject interface).

Float64Max (ValueExtractor::View vExtractor)

Construct a Float64Max aggregator.

virtual void init (bool fFinal)

Initialize the aggregation result.

Parameters:

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.

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

Constructor & Destructor Documentation

Float64Max ( ValueExtractor::View vExtractor ) [protected]
