Syntax
public class DoubleMax : AbstractDoubleAggregator, IParallelAwareAggregator, IEntryAggregator, IPortableObject
Remarks

All the extracted objects (Byte, Int16, Int32, Int64, Single, Double) will be treated as Double values. If the collection of entries is empty, a null result is returned.

Constructors

DoubleMax()

Default constructor.

Declaration
public DoubleMax()

DoubleMax(string)

Construct a DoubleMax aggregator.

Declaration
public DoubleMax(string member)
Parameters
Type Name Description
string member

The name of the member that returns a value in the form of any .NET object out of Byte, Int16, Int32, Int64, Single, Double.

DoubleMax(IValueExtractor)

Construct a DoubleMax aggregator.

Declaration
public DoubleMax(IValueExtractor extractor)
Parameters
Type Name Description
IValueExtractor extractor

The extractor that provides a value in the form of any .NET object out of Byte, Int16, Int32, Int64, Single, Double.

Methods

Init(bool)

Initialize the aggregation result.

Declaration
protected override void Init(bool isFinal)
Parameters
Type Name Description
bool isFinal

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.
Overrides

Process(object, bool)

Incorporate one aggregatable value into the result.

Declaration
protected override void Process(object o, bool isFinal)
Parameters
Type Name Description
object o

The value to incorporate into the aggregated result.
bool isFinal

true to indicate that the given object is a partial result returned by a parallel aggregator.
Overrides
Remarks

If the isFinal 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 IInvocableCacheEntry.
