SyntaxC#
public abstract class AbstractDoubleAggregator : AbstractAggregator
The AbstractDoubleAggregator type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | AbstractDoubleAggregator |
Default constructor.
|
| AbstractDoubleAggregator(String) |
Construct a AbstractDoubleAggregator aggregator.
|
| AbstractDoubleAggregator(IValueExtractor) |
Construct a AbstractDoubleAggregator aggregator.
|
Properties| Name | Description | |
|---|---|---|
 | Extractor |
Determine the IValueExtractor whose values this
aggregator is aggregating.
(Inherited from AbstractAggregator.) |
| ParallelAggregator |
Get an aggregator that can take the place of this aggregator in
situations in which the IInvocableCache can
aggregate in parallel.
(Inherited from AbstractAggregator.) |
Methods| Name | Description | |
|---|---|---|
| Aggregate |
Process a set of IInvocableCacheEntry objects
in order to produce an aggregated result.
(Inherited from AbstractAggregator.) |
| AggregateResults |
Aggregate the results of the parallel aggregations.
(Inherited from AbstractAggregator.) |
| Equals |
Compares this object with another object for equality.
(Inherited from AbstractAggregator.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| FinalizeResult |
Obtain the result of the aggregation.
(Overrides AbstractAggregatorFinalizeResult(Boolean).) |
| GetHashCode |
Returns a hash code value for this object.
(Inherited from AbstractAggregator.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Init |
Initialize the aggregation result.
(Overrides AbstractAggregatorInit(Boolean).) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Process |
Incorporate one aggregatable value into the result.
(Inherited from AbstractAggregator.) |
| ReadExternal |
Restore the contents of a user type instance by reading its state
using the specified IPofReader object.
(Inherited from AbstractAggregator.) |
| ToString |
Provide a human-readable representation of this object.
(Inherited from AbstractAggregator.) |
| WriteExternal |
Save the contents of a POF user type instance by writing its
state using the specified IPofWriter object.
(Inherited from AbstractAggregator.) |
Fields| Name | Description | |
|---|---|---|
 | m_count |
The count of processed entries.
|
| m_isParallel |
Set to true if this aggregator realizes that it is going to be
used in parallel.
(Inherited from AbstractAggregator.) |
| m_result |
The running result value.
|
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.
