The AbstractAggregator type exposes the following members.

Constructors
  NameDescription
Public methodAbstractAggregator
Default constructor.

Properties
  NameDescription
Public propertyExtractor
Determine the IValueExtractor whose values this aggregator is aggregating.
Public propertyParallelAggregator
Get an aggregator that can take the place of this aggregator in situations in which the IInvocableCache can aggregate in parallel.
Top
Methods
  NameDescription
Public methodAggregate
Process a set of IInvocableCacheEntry objects in order to produce an aggregated result.
Public methodAggregateResults
Aggregate the results of the parallel aggregations.
Public methodEquals
Compares this object with another object for equality.
(Overrides ObjectEquals(Object).)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Protected methodFinalizeResult
Obtain the result of the aggregation.
Public methodGetHashCode
Returns a hash code value for this object.
(Overrides ObjectGetHashCode.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodInit
Initialize the aggregation result.
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodProcess
Incorporate one aggregatable value into the result.
Public methodReadExternal
Restore the contents of a user type instance by reading its state using the specified IPofReader object.
Public methodToString
Provide a human-readable representation of this object.
(Overrides ObjectToString.)
Public methodWriteExternal
Save the contents of a POF user type instance by writing its state using the specified IPofWriter object.

Fields
  NameDescription
Protected fieldm_isParallel
Set to true if this aggregator realizes that it is going to be used in parallel.

Remarks
For aggregators which only run within the Coherence cluster (most common case), the .NET Init, Process, FinalizeResult, Aggregate, and AggregateResults methods can be left unimplemented.
