SyntaxC#
public class CompositeAggregator : IEntryAggregator, IPortableObject
The CompositeAggregator type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | CompositeAggregator |
Default constructor.
|
 | CompositeAggregator(IEntryAggregator) |
Construct a CompositeAggregator based on a specified
IEntryAggregator array.
|
Methods| Name | Description | |
|---|---|---|
| Aggregate |
Process a set of IInvocableCacheEntry objects
in order to produce an aggregated result.
|
 | CreateInstance |
Create an instance of CompositeAggregator based on a specified
IEntryAggregator array.
|
| Equals |
Compare the CompositeAggregator with another object to determine
equality.
(Overrides ObjectEquals(Object).) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode |
Determine a hash value for the CompositeAggregator object
according to the general object.GetHashCode() contract.
(Overrides ObjectGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadExternal |
Restore the contents of a user type instance by reading its state
using the specified IPofReader object.
|
| ToString |
Return a human-readable description for this CompositeAggregator.
(Overrides ObjectToString.) |
| WriteExternal |
Save the contents of a POF user type instance by writing its
state using the specified IPofWriter object.
|
Fields| Name | Description | |
|---|---|---|
 | m_aggregators |
The underlyig IEntryAggregator array.
|
RemarksThe size of the returned list will always be equal to the length of the aggregators' array.
Note: Unlike many other concrete IEntryAggregator implementations that are constructed directly, instances of CompositeAggregator should only be created using the factory method CreateInstance(IEntryAggregator).
